Determine whether each equation is always, sometimes, or never true. 2x + 7 - x = 3 + x + 4
Always
Sometimes
Never
Empty Set

I said never but I want see if thats right

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!
