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

Answer:40%

Explanation:

Answer 2

Let a= apple pies, and s= strawberry pies
4/5 s= a
24 + s = a
therefore:
the 1/5 difference between s and a is 24
s: 24 x 5 =120
a: 24 x 4 = 96
now, find the percentage of blueberry pies:
blueberry/total
144/ (144+120+96)
144/360
=0.4
=40%
