For every car she sells, she earns a 500 dollar fee.
1 car = $500
She sells 4 cars, and we need to find out how much she earns in fees.
4 cars = $ ?
We can set up a proportion to find out how much she earns.
[tex]\frac{1}{500} =\frac{4}{?}[/tex]
Cross multiply
1*? = 2,000
Amount she earns from fees is $2000
