Vanessa and Joelle made some cranberry puffs and chocolate chip puffs. Vanessa made 10 more cranberry puffs than chocolate chip puffs. Joelle made 108 more chocolate chip puffs than cranberry puffs. The total number of cranberry puffs made up 43% of the total number of puffs they made. How many cranberry puffs did they make altogether?

Number of chocolate chip puffs		Number of cranberry puffs
57%		43%
Vanessa	Joelle	Vanessa	Joelle
1 u	1 p + 108	1 u + 10	1 p

Vanessa
Number of chocolate chip puffs = 1 u
Number of cranberry puffs = 1 u + 10

Joelle
Number of cranberry puffs = 1 p
Number of chocolate chip puffs = 1 p + 108

Number of chocolate chip puffs in percent
= 100% - 43%
= 57%

1 u + 10 + 1 p = 43% --- (1)
1 u + 1 p + 108 = 57% --- (2)

(2) - (1)
57% - 43% = 108 - 10
14% = 98

1% = 98 ÷ 14 = 7

Number of cranberry puffs that they made altogether
= 43%
= 43 x 7
= 301

Answer(s): 301
