Sabrina and Joelle made some chocolate chip puffs and cherry puffs. Sabrina made 37 more chocolate chip puffs than cherry puffs. Joelle made 141 more cherry puffs than chocolate chip puffs. The total number of chocolate chip puffs made up 24% of the total number of puffs they made. How many cherry puffs did they make altogether?

Number of cherry puffs		Number of chocolate chip puffs
76%		24%
Sabrina	Joelle	Sabrina	Joelle
1 u	1 p + 141	1 u + 37	1 p

Sabrina
Number of cherry puffs = 1 u
Number of chocolate chip puffs = 1 u + 37

Joelle
Number of chocolate chip puffs = 1 p
Number of cherry puffs = 1 p + 141

Number of cherry puffs in percent
= 100% - 24%
= 76%

1 u + 37 + 1 p = 24% --- (1)
1 u + 1 p + 141 = 76% --- (2)

(2) - (1)
76% - 24% = 141 - 37
52% = 104

1% = 104 ÷ 52 = 2

Number of cherry puffs that they made altogether
= 76%
= 76 x 2
= 152

Answer(s): 152
