# Thread: Meeting Sales Targets exercise

1. ## Meeting Sales Targets exercise

I cannot seem to solve this:

A salesman's monthly commission is 15% on all sales over \$12,000. If his goal is to make a commission of at least \$3,000/month, what minimum monthly sales figures must he attain?

I do know the answer is \$32,000, but cannot find the solution.

Thanks!

Solve $0.15 (x - 12,000) \geq 3000$

$\Rightarrow 0.15x - 1800 \geq 3000$.
