3x5 =
15 u |
2x5 =
10 u |
Before

5x3 =
15 u |
10 u |
Change

- 3x3 =
- 9 u |
- 2 |
After

2x3 =
6 u |
10 u - 2 |
The number of macarons at first is repeated. Make the number of macarons at first the same. LCM of 3 and 5 is 15.
Total number of pastries left
= 6 u + 10 u - 2
= 16 u - 2
16 u - 2 = 94
16 u = 94 + 2
16 u = 96
1 u = 96 ÷ 16 = 6
Number of pastries that Tom sold
= 9 u + 2
= 9 x 6 + 2
= 54 + 2
= 56
Answer(s): 56
