Tina made 159 more cranberry croissants than strawberry croissants. The total number of strawberry croissants made up 44% of the total number of croissants they made. How many cranberry croissants did they make altogether?

Number of cranberry croissants		Number of strawberry croissants
56%		44%
Zara	Tina	Zara	Tina
1 u	1 p + 159	1 u + 15	1 p

Zara
Number of cranberry croissants = 1 u
Number of strawberry croissants = 1 u + 15

Tina
Number of strawberry croissants = 1 p
Number of cranberry croissants = 1 p + 159

Number of cranberry croissants in percent
= 100% - 44%
= 56%

1 u + 15 + 1 p = 44% --- (1)
1 u + 1 p + 159 = 56% --- (2)

(2) - (1)
56% - 44% = 159 - 15
12% = 144

1% = 144 ÷ 12 = 12

Number of cranberry croissants that they made altogether
= 56%
= 56 x 12
= 672

Answer(s): 672
