Sabrina and Irene made some apple croissants and cherry croissants. Sabrina made 128 more apple croissants than cherry croissants. Irene made 180 more cherry croissants than apple croissants. The total number of apple croissants made up 37% of the total number of croissants they made. How many cherry croissants did they make altogether?

Number of cherry croissants		Number of apple croissants
63%		37%
Sabrina	Irene	Sabrina	Irene
1 u	1 p + 180	1 u + 128	1 p

Sabrina
Number of cherry croissants = 1 u
Number of apple croissants = 1 u + 128

Irene
Number of apple croissants = 1 p
Number of cherry croissants = 1 p + 180

Number of cherry croissants in percent
= 100% - 37%
= 63%

1 u + 128 + 1 p = 37% --- (1)
1 u + 1 p + 180 = 63% --- (2)

(2) - (1)
63% - 37% = 180 - 128
26% = 52

1% = 52 ÷ 26 = 2

Number of cherry croissants that they made altogether
= 63%
= 63 x 2
= 126

Answer(s): 126
