Fraction of the cranberry wafers left
= 1 -
14=
34 The number of cranberry and vanilla wafers in the end is the same.
Total number of wafers at first
= 4 u + 3 u + 17
= 7 u + 17
7 u + 17 = 59
7 u = 59 - 17
7 u = 42
1 u = 42 ÷ 7 = 6
Number of vanilla wafers at first
= 3 u + 17
= 3 x 6 + 17
= 18 + 17
= 35
Answer(s): 35
