- 5x5 =
- 25 u |

After

1x5 =
5 u |
18 u - 4 |
The number of cupcakes at first is repeated. Make the number of cupcakes at first the same. LCM of 5 and 6 is 30.
Total number of pastries left
= 5 u + 18 u - 4
= 23 u - 4
23 u - 4 = 88
23 u = 88 + 4
23 u = 92
1 u = 92 ÷ 23 = 4
Number of more cupcakes than puffs that Ian sold
= 25 u - 4
= 25 x 4 - 4
= 100 - 4
= 96
Answer(s): 96
