The questions is, when z=9, 3z = ? When you multiply 3*9, you get 27
A.
It cost 9 dollars per person so 9x
and you need to add the additional 3 dollars for parking
so y = 9x + 3
total entry parking
The answer is (14) just add them all up
I think the way that you do is 5/5+3=5/8
5/8*4=2.5 so 2.5 is the answer
