Fanny and Roshel made some blueberry puffs and apricot puffs. Fanny made 20 more blueberry puffs than apricot puffs. Roshel made 200 more apricot puffs than blueberry puffs. The total number of blueberry puffs made up 32% of the total number of puffs they made. How many blueberry puffs did they make altogether?

Number of apricot puffs		Number of blueberry puffs
68%		32%
Fanny	Roshel	Fanny	Roshel
1 u	1 p + 200	1 u + 20	1 p

Fanny
Number of apricot puffs = 1 u
Number of blueberry puffs = 1 u + 20

Roshel
Number of blueberry puffs = 1 p
Number of apricot puffs = 1 p + 200

Number of apricot puffs in percent
= 100% - 32%
= 68%

1 u + 20 + 1 p = 32% --- (1)
1 u + 1 p + 200 = 68% --- (2)

(2) - (1)
68% - 32% = 200 - 20
36% = 180

1% = 180 ÷ 36 = 5

Number of blueberry puffs that they made altogether
= 32%
= 32 x 5
= 160

Answer(s): 160
