Fraction of the blueberry wafers left
= 1 -
14=
34 The number of blueberry and apple wafers in the end is the same.
Total number of wafers at first
= 4 u + 3 u + 17
= 7 u + 17
7 u + 17 = 94
7 u = 94 - 17
7 u = 77
1 u = 77 ÷ 7 = 11
Number of apple wafers at first
= 3 u + 17
= 3 x 11 + 17
= 33 + 17
= 50
Answer(s): 50
