Answer:
y =
Step-by-step explanation:
since y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
to find k use the given condition y = 9 when x = 72
k = = = , hence
y = × x =
Answer:
the cylinder

if you look at it the cylinder is the biggest and largest and take must of the space
Equation #1 97.20=9y
Equation #2 123.40= 8x+10(10.80)
I got 10.80 when I divided 97.20/9
cost of burritos is 10.80
