Simplify 6.4k + 2.8 – 0.75 + 1.8k.

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

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!
