12 u |
15 u - 14 |
The number of macarons at first is repeated. Make the number of macarons at first the same. LCM of 4 and 5 is 20.
Total number of pastries left
= 12 u + 15 u - 14
= 27 u - 14
27 u - 14 = 229
27 u = 229 + 14
27 u = 243
1 u = 243 ÷ 27 = 9
Number of pastries that Henry sold
= 8 u + 14
= 8 x 9 + 14
= 72 + 14
= 86
Answer(s): 86
