5x6 =
30 u |
3x6 =

- 5x5 =

After

1x5 =
5 u |
18 u - 19 |
The number of croissants at first is repeated. Make the number of croissants at first the same. LCM of 5 and 6 is 30.
Total number of pastries left
= 5 u + 18 u - 19
= 23 u - 19
23 u - 19 = 96
23 u = 96 + 19
23 u = 115
1 u = 115 ÷ 23 = 5
Number of more croissants than wafers that Jack sold
= 25 u - 19
= 25 x 5 - 19
= 125 - 19
= 106
Answer(s): 106
