- 3x5 =
- 15 u |
- 8 |
After

1x5 =
5 u |
12 u - 8 |
The number of macarons at first is repeated. Make the number of macarons at first the same. LCM of 5 and 4 is 20.
Total number of pastries left
= 5 u + 12 u - 8
= 17 u - 8
17 u - 8 = 43
17 u = 43 + 8
17 u = 51
1 u = 51 ÷ 17 = 3
Number of more macarons than tarts that Sean sold
= 15 u - 8
= 15 x 3 - 8
= 45 - 8
= 37
Answer(s): 37
