Question

A car dealership pays you 4% commission on your first $8,000 in car sales and 8% commission on additional sales over the $8,000. If you made $9,000 in car sales, how much is your commission?

Answer 1

the first thing that you should do is change 4% to a decimal

Answer 2

We can represent it by this formula:

\(0.08(x-8,000)+0.04(8,000)\) where \(x≥8,000\)
plug in x=9000 into the formula

Answer 3

Thats good. I was gonna get to that, but I wanted to explain it first
