Question

Mr. Smith baked 144 blueberry pies, some strawberry pies, and some apple pies. The number of apple pies is 4\5 of the number of strawberry pies. There are 24 more strawberry pies than apple pies. What percent of the pies are blueberry pies?

Answer 1

b = 144
a = 4/5s
s = a + 24

s = 4/5s + 24
5/5s - 4/5s = 24
1/5s = 24
s = 24 * 5
s = 120

a = 4/5s
a = 4/5(120)
a = 480/5
a = 96

blueberry pies = 144
total of all pies = 144 + 120 + 96 = 360

percent of blueberry pies is : 144/360 = 0.40 = 40% <==

Answer 2

Answer:b = 144

a = 4/5s

s = a + 24

s = 4/5s + 24

5/5s - 4/5s = 24

1/5s = 24

s = 24 * 5

s = 120

a = 4/5s

a = 4/5(120)

a = 480/5

a = 96

blueberry pies = 144

total of all pies = 144 + 120 + 96 = 360

percent of blueberry pies is : 144/360 = 0.40 = 40% <==

This is right
