Lucy and Nora made some chocolate chip buns and cherry buns. Lucy made 10 more chocolate chip buns than cherry buns. Nora made 34 more cherry buns than chocolate chip buns. The total number of chocolate chip buns made up 44% of the total number of buns they made. How many cherry buns did they make altogether?

Number of cherry buns		Number of chocolate chip buns
56%		44%
Lucy	Nora	Lucy	Nora
1 u	1 p + 34	1 u + 10	1 p

Lucy
Number of cherry buns = 1 u
Number of chocolate chip buns = 1 u + 10

Nora
Number of chocolate chip buns = 1 p
Number of cherry buns = 1 p + 34

Number of cherry buns in percent
= 100% - 44%
= 56%

1 u + 10 + 1 p = 44% --- (1)
1 u + 1 p + 34 = 56% --- (2)

(2) - (1)
56% - 44% = 34 - 10
12% = 24

1% = 24 ÷ 12 = 2

Number of cherry buns that they made altogether
= 56%
= 56 x 2
= 112

Answer(s): 112
