Fraction of the banana muffins left
= 1 -
16=
56 The number of banana and vanilla muffins in the end is the same.
Total number of muffins at first
= 6 u + 5 u + 20
= 11 u + 20
11 u + 20 = 108
11 u = 108 - 20
11 u = 88
1 u = 88 ÷ 11 = 8
Number of vanilla muffins at first
= 5 u + 20
= 5 x 8 + 20
= 40 + 20
= 60
Answer(s): 60
