BUSINESS MATHEMATICS Name: _____________________________________ Grade Level:________________ Section: ______________________________________ Date: _____________________ LEARNING ACTIVITY SHEET Forms of Commission Background Information of Learners Commission is a fee that a business pays to a salesperson (agent) in exchange for his services in either facilitating, supervising, or completing a sale. The commission may be based on a flat arrangement or as a percentage of the revenue generated by a salesperson. In other words, commission (remuneration) is a form of payment to an agent for services rendered. There are 3 forms of commission 1. Straight Commission is when a person is paid a % of sales. Example: Alicia receives 20% on beauty products she sells. If she sells P30,000.00 worth of beauty products, how much does Alicia make in commission? So, from P30,000.00 sale, the commission is computed as P30,000 x 20%= P6,000. 2. Salary commission is when a person gets paid a salary and a percentage of his/her sales Example: Maria decides to work in another department store that will pay her P35,000.00 per month and 3% of any sales above P300,000.00. If he sold goods worth P450,000, what is his gross pay? Solution: P450,000-P300,000 = P150,000 P150,000 x 3% = P4,500 Gross pay = P35,000.00 + P4,500.00 Gross pay= P39,500.00 3. Graduated commission a commission, which varies according to how much sales, is made. Example: Elijah works for a company that pays him 3% on the 1st P150,000 sold, 4% on the next P200,000 sold and 5% on all sales above P350,000. What is his gross pay if he sells P450,000? Solution: P150,000 x 3% = P4,500 P200,000 x 4% = P8,000 P100,000 x 5% = P5,000 Total Gross pay = P4,500 + P8,000 + P,5000 = P16,500 Learning competency with code Illustrate the different types of commissions.

BUSINESS MATHEMATICS Name of Learner: __________________________ Grade Level: _______________ Section: _________________________________ Date: _____________________ LEARNING ACTIVITY SHEET COMMISSION ON CASH BASIS AND INSTALLMENT BASIS Background Information for Learners After learning commission and its different types in the previous lesson, you will now compute commissions on cash basis and commissions on installment basis. You have learned that a commission is a fee that a business pays to a salesman or an agent in exchange for his services in either facilitating, supervising, or completing a sale. Commission has three types: straight, salary plus and graduated commission. Now, you will focus on computing commissions that are in cash or installment basis. Not all employees depend on commission alone, some have their basic salary with an additional commission depending on the commission rate given by company. KEY FACTS: ❖ Computing commissions on cash basis is similar to computing straight commissions. ❖ Straight Commission or revenue commission is only primarily based on a percentage of sales. This is profitable if you are promoting a high-priced item. ❖ If the sales are on installment basis, corporations do not give commissions primarily based on sales. Rather, they are given fee primarily based on collection, that is, payment made via buyers. EXAMPLE 1 Mario works at Matatag Gadget Store. For every unit purchase of a laptop, he gets 6% commission. In a month, he was able to sell 15 laptops costing PhP 30,000 each. How much was his total commission for such cash sales? Solution: Total Sales = PhP 30,000/laptop x 15 laptops = PhP 450,000 Cash commission = 6% of PhP 450,000 = PhP 450,000 x 6% = PhP 450,000 x 0.06 = PhP27,000 EXAMPLE 2 Masipag Appliance Center offers a 3% monthly commission on sales in an installment basis. Assuming a sale of PhP 120,000 paid in monthly installments of PhP 10,000 made by the buyer. a. What would be the monthly commission? b. What would be the total commission within 6 months of payment? 7

Solution: a. 3% of PhP 10,000 = PhP 10,000 x 3% = PhP 10,000 x 0.03 = PhP 300 The monthly commission would be PhP 300. b. (PhP 10,000 x 3%) x 6 months = (PhP 10,000 x 0.03) x 6 = PhP 300 x 6 = Php 1,800 The total commission within 6 months is PhP 1800. Learning Competency Compute commissions on cash basis and commission on installment basis. ABM_BM11BS-IIa-12 PRACTICE EXERCISE 1 Directions: Answer the following on the space provided.

BUSINESS MATHEMATICS Name of Learner: __________________________ Grade Level: _______________ Section: _________________________________ Date: _____________________ LEARNING ACTIVITY SHEET DOWN PAYMENT, GROSS BALANCE AND CURRENT INCREASED BALANCE Background Information for Learners One of the keys in understanding about commission and interest is understanding the concepts like down payment, gross balance, and current increased balance. In the business world, transaction between the buyer and seller is not always on the cash basis, in an installment basis, there is a down payment that a buyer needs to give in order to purchase the item he wishes to have. Likewise, during the payment period, due to uncertain situations, the buyer sometimes pays the monthly payment late, as a result, penalty will be charged. In this activity, you will encounter scenarios mentioned above. KEY FACTS: ❖ Down payment is a first payment that one makes when one buys something with an agreement to pay the rest later. Down payment is usually a certain percent of the purchase price of the property, it is generally called the buyer’s equity. ❖ Investopedia.com defines gross balance or book balance as the banking term to describe funds on deposit after adjustments have been made for reserve requirements, checks that have yet to clear, deposits in transit, or other pending deductions from an account. In other words, the book balance represents the actual money accessible for a company to spend. ❖ The gross balance is a measure of what the financial institution has on hand before adding or subtracting regulatory duties and items that will quickly show up on its book. ❖ Current increased balance refers to the total amount you have to pay that includes penalties or interest incurred by unpaid balance from a loan or payment you are supposed to have made but was not able to do so on time. EXAMPLE 1: Down payment When one purchases a vehicle or any large item not via cash however installment terms, normally, a certain down payment is required of the buyer. Car sellers usually require a minimum down payment, which is generally 20% of the total value of the vehicle being purchased. The interest on the remaining balance is then computed depending on the number of years a buyer would want to amortize the remaining balance. If a car costs PhP1,500,000 11

and a minimum 20% down payment is required by the company, then the buyer will have an initial cash out of PhP300,000; that is, 20% (1,500,000) = PhP300,000. The remaining PhP1,200,000 will be amortized monthly and the amount of monthly amortization depends on the number of years the buyer will want to pay the loan. Normally, buyers prefer a 3-year or 5-year payment period. The lesser the number of years, the lesser the total amount of money paid as interest to the loan. But with this arrangement, the monthly amortization will be considerably higher than when one chooses to pay the balance for longer number of years. EXAMPLE 2: Gross Balance A simple case of gross balance refers to what is readily accessible to use based totally on the bank deposits. For example, a check amounting to PhP5,000 that has been deposited today may not be withdrawn the next day because it has not cleared yet. If your financial institution passbook presently contains PhP40,000, you may additionally not be capable to withdraw the complete quantity but because your gross balance is solely PhP35,000 since the check has not been cleared yet. EXAMPLE 3: Current Increased Balance As of this month’s cut-off date, the current total amount due from your purchases using your credit card is PhP 95,400. The minimum required payment is 5% of the total amount due. If you pay only the minimum required payment, a financing charge of 3% of the remaining balance will be charged to the next bill. Assuming you refrain from using your credit card on any of your purchases for the next 3 months and the financing charge of 3% is charged every billing period, show your expected monthly bill for the next 3 months. Solution: Given the current bill of PhP 95,400, the minimum required payment is 0.05(95,400) = PhP4,770. If only the minimum required payment is paid, then the remaining debt balance is 95,400 - 4,770 = PhP 90,630. Assuming there are no credit bill transactions for the next 3 months and only the minimum required payment each month is paid, the table below shows the monthly total amount due for each of the next 3 months. Time t Total amount due for the month Minimum required payment for (month) the month 0 PhP 95,450 0.05(95,450)= PhP 4,770 1 (95,450 - 4,770) + .03(95,450 - 4,770) 0.05(93,348.9) = PhP 4,667.445 =90,630 + .03(90,630) 2 =1.03(90,630) 0.05(91,341.90)= PhP 4,567.095 = PhP 93,348.9 3 1.03(93,348.9 – 4,667.445) 0.05(89,378.049)= PhP 4,468.90 =1.03(88,681.455) = PhP 91,341.90 1.03(91,341.90 – 4,567.095) =1.03 (86,774.805) = PhP 89,378.049 Observe that for the next 3 months, a total of PhP 13,703.44 has already been paid for the credit card bills. However, only PhP 6,071.951 (95,450-89,378.049) has been deducted so 12

far from the original debt of PhP95,450. Hence, every time we keep paying only the required minimum payment, more money goes to interest payments rather than payment of the actual debt. From the above example, your minimum required payment of PhP4,770 serves as your down payment for your loan of PhP 99,386.59 leaving you with a balance of PhP 94,417.26 at the start of the month. However, because there is a finance charge of 3%, if you are not able pay for the next month, your current increased balance will become PhP 93,348.9. Learning Competency Compute down payment, gross balance, and current increased balance. ABM_BM11BS-IIa- 13 PRACTICE EXERCISE 1 Directions: Complete the necessary data in the tables below. (1 point each entry) 1. For the month of June, the current total amount due of purchases using your credit card is PhP 105, 000. The minimum required payment is 6% of the total amount due. If you pay only the minimum required payment, a financing charge of 2.5% of the remaining balance will be charged to the next bill. Assuming you refrain from using your credit card on any of your purchases for the next 4 months and the financing charge of 2.5% is charged every billing period, show your expected monthly bill for the next 4 months.
