Fraction of the cherry wafers left
= 1 -
16=
56 The number of cherry and blueberry wafers in the end is the same.
Total number of wafers at first
= 6 u + 5 u + 20
= 11 u + 20
11 u + 20 = 75
11 u = 75 - 20
11 u = 55
1 u = 55 ÷ 11 = 5
Number of blueberry wafers at first
= 5 u + 20
= 5 x 5 + 20
= 25 + 20
= 45
Answer(s): 45
