1.) 21

2.) 0.453

3.) 1.5

4.) 48

5.) $ 22

step-by-step explanation:

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
