What is the area, in square units, of ADEF with D(5,-1), E(1,-4), and F(-5,4)? O 25 square units
O 37.5 square units
O 50 square units
O 75 square units

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!
