# Math Help - 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! 2. Originally Posted by clari I cannot seem to solve this: A salesman's monthly commission is 15% on all sales over$12,000.

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

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