Question

9. Jeremy receives a base salary of $25,000 plus 5% commission on his sales. Jeremy received a total salary of

$45,000 last year. How much were his total sales?
a. $20,000
b. $70,000
c. $400,000
d $900,000

Answer 1

c. $400,000

Explanation:

Let his total sales be $x.

Salary + commission =$45000

`\therefore \: 25000 + 5 \% \: of \: x = 45000 \\ \\ (5)/(100) x = 45000 - 25000 \\ \\ (1)/(20)x = 20000 \\ \\ x = 20 * 20000 \\ \\ x = \$\:400, 000`
