Hilda and Winnie made some banana croissants and cherry croissants. Hilda made 16 more banana croissants than cherry croissants. Winnie made 176 more cherry croissants than banana croissants. The total number of banana croissants made up 40% of the total number of croissants they made. How many cherry croissants did they make altogether?

Number of cherry croissants		Number of banana croissants
60%		40%
Hilda	Winnie	Hilda	Winnie
1 u	1 p + 176	1 u + 16	1 p

Hilda
Number of cherry croissants = 1 u
Number of banana croissants = 1 u + 16

Winnie
Number of banana croissants = 1 p
Number of cherry croissants = 1 p + 176

Number of cherry croissants in percent
= 100% - 40%
= 60%

1 u + 16 + 1 p = 40% --- (1)
1 u + 1 p + 176 = 60% --- (2)

(2) - (1)
60% - 40% = 176 - 16
20% = 160

1% = 160 ÷ 20 = 8

Number of cherry croissants that they made altogether
= 60%
= 60 x 8
= 480

Answer(s): 480
