Answer 17

So how do I calculate the amount of pizza per dollar?

Answer 18

\[\frac{$}{\text{inches}^2}=\frac{\text{Total cost of that pizza}}{\text{Area of that pizza}}\]

Answer 19

Answer 20

201-154=47
154-113=41
201-113=88

Answer 21

\[\frac{\text{inches}^2}{$}=\frac{\text{Area of that pizza}}{\text{Total cost of that pizza}}\]

Answer 22
