Number of cherry muffins		Number of banana muffins
57%		43%
Wendy	Tiffany	Wendy	Tiffany
1 u	1 p + 96	1 u + 54	1 p

Wendy
Number of cherry muffins = 1 u
Number of banana muffins = 1 u + 54

Tiffany
Number of banana muffins = 1 p
Number of cherry muffins = 1 p + 96

Number of cherry muffins in percent
= 100% - 43%
= 57%

1 u + 54 + 1 p = 43% --- (1)
1 u + 1 p + 96 = 57% --- (2)

(2) - (1)
57% - 43% = 96 - 54
14% = 42

1% = 42 ÷ 14 = 3

Number of banana muffins that they made altogether
= 43%
= 43 x 3
= 129

Answer(s): 129
