Question

A salesperson is selling cooking sets for $120 each. The salesperson receives 22.5% of the sales prices as commission. The salesperson sells a total of 4 units on Monday but an unknown number of units on Tuesday. The salesperson made a combined total of $351 commission for those two days. Write an equation that could be used to find the number of cooking sets x sold on Tuesday. Then solve the equation.

Answer 1

4(120)(.225) + x (120)(.225) = $351

9 units sold on Tuesday

Explanation:

1. You can easily figure how much money was made on Monday by multiply the total units sold by the price per unit by the commission in decimal form. Here you get $108.

2. Subtract that $108 from the $351 made on both days and you get $243 made on Tuesday.

3. The equation is now the unknown number of units sold (x) times the price ($120) times the commission is decimal form (.225) equals $243.

4. Since 120 times .225 is equal to 27, the equation now becomes 9x is equal to 243.

5. Divide 243 by 27 for your answer.
