Your answer would be 3.4
Anything under 5 it stays the same and anything over 5 it goes up one
Surface area= 2(6x15)+2(7x15)+2(6x7)
=180+210+84
=474m
Volume=15x6x7
=630m^2
Cost = (3,500) * (1.04)^years
Cost = (3,500) * (1.04)^4

You’re going it plug in the inputs for every input for the letter x. So the first one, fx= -4(-2)+1= 9. The second one fx= -4(0)+1=1. The third one fx= -4(5)+1=19.
