Answer:
The difference in price between a small pizza and a medium pizza is $0.81
Step-by-step explanation:
Small pizza
Side = 5inch
Area = 25 sq.in
Cost = $4 +0.04*25
= 4 + 1.25 = $5.25
Medium pizza
Side = 8inche
Area = 64 sq.in
Cost = 3.50 + 0.04*64 = $6.06
Difference = Medium pizza - small pizza
= 6.06 - 5.25
= $0.81
27$ because you do 20*15*12 then 3600*0.09 and divide that answer by 12 which is 27
