8 u - 15 |
The number of muffins at first is repeated. Make the number of muffins at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 8 u - 15
= 9 u - 15
9 u - 15 = 39
9 u = 39 + 15
9 u = 54
1 u = 54 ÷ 9 = 6
Number of more muffins than macarons that Harry sold
= 5 u - 15
= 5 x 6 - 15
= 30 - 15
= 15
Answer(s): 15
