Fraction of the chocolate chip shortbreads left
= 1 -
13=
23 The number of chocolate chip and apricot shortbreads in the end is the same.
Total number of shortbreads at first
= 3 u + 2 u + 17
= 5 u + 17
5 u + 17 = 62
5 u = 62 - 17
5 u = 45
1 u = 45 ÷ 5 = 9
Number of apricot shortbreads at first
= 2 u + 17
= 2 x 9 + 17
= 18 + 17
= 35
Answer(s): 35
