9 u |
20 u - 7 |
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
= 9 u + 20 u - 7
= 29 u - 7
29 u - 7 = 254
29 u = 254 + 7
29 u = 261
1 u = 261 ÷ 29 = 9
Number of more macarons than cupcakes that Owen sold
= 6 u - 7
= 6 x 9 - 7
= 54 - 7
= 47
Answer(s): 47
