Answer:
Step-by-step explanation:
Mae king earns a weekly salary of $305 plus a 7.5% commission on sales at a gift shop. This means that the total amount that she can earn in a week is not fixed. If in a week, she sold 4,300 worth of merchandise, her commission on this amount of sales will be 7.5 % of 4,300
Commission on sales = 7.5/100× 4300 = 0.075×4300= $332.25
Amount of money made for the week will be the sum of her weekly salary and the commission earned on sales. It becomes
305 + 332.25 = $627.5
