Marion made 188 more chocolate chip croissants than apricot croissants. The total number of apricot croissants made up 39% of the total number of croissants they made. How many apricot croissants did they make altogether?

Number of chocolate chip croissants		Number of apricot croissants
61%		39%
Vanessa	Marion	Vanessa	Marion
1 u	1 p + 188	1 u + 78	1 p

Vanessa
Number of chocolate chip croissants = 1 u
Number of apricot croissants = 1 u + 78

Marion
Number of apricot croissants = 1 p
Number of chocolate chip croissants = 1 p + 188

Number of chocolate chip croissants in percent
= 100% - 39%
= 61%

1 u + 78 + 1 p = 39% --- (1)
1 u + 1 p + 188 = 61% --- (2)

(2) - (1)
61% - 39% = 188 - 78
22% = 110

1% = 110 ÷ 22 = 5

Number of apricot croissants that they made altogether
= 39%
= 39 x 5
= 195

Answer(s): 195
