= 1 -
17=
67 The number of cherry and chocolate chip shortbreads in the end is the same.
Total number of shortbreads at first
= 7 u + 6 u + 19
= 13 u + 19
13 u + 19 = 84
13 u = 84 - 19
13 u = 65
1 u = 65 ÷ 13 = 5
Number of chocolate chip shortbreads at first
= 6 u + 19
= 6 x 5 + 19
= 30 + 19
= 49
Answer(s): 49
