Linda and Fiona made some banana puffs and apricot puffs. Linda made 29 more banana puffs than apricot puffs. Fiona made 191 more apricot puffs than banana puffs. The total number of banana puffs made up 23% of the total number of puffs they made. How many banana puffs did they make altogether?

Number of apricot puffs		Number of banana puffs
77%		23%
Linda	Fiona	Linda	Fiona
1 u	1 p + 191	1 u + 29	1 p

Linda
Number of apricot puffs = 1 u
Number of banana puffs = 1 u + 29

Fiona
Number of banana puffs = 1 p
Number of apricot puffs = 1 p + 191

Number of apricot puffs in percent
= 100% - 23%
= 77%

1 u + 29 + 1 p = 23% --- (1)
1 u + 1 p + 191 = 77% --- (2)

(2) - (1)
77% - 23% = 191 - 29
54% = 162

1% = 162 ÷ 54 = 3

Number of banana puffs that they made altogether
= 23%
= 23 x 3
= 69

Answer(s): 69
