3x3 =
9 u |
10 u - 8 |
The number of muffins at first is repeated. Make the number of muffins at first the same. LCM of 3 and 5 is 15.
Total number of pastries left
= 9 u + 10 u - 8
= 19 u - 8
19 u - 8 = 106
19 u = 106 + 8
19 u = 114
1 u = 114 ÷ 19 = 6
Number of pastries that Paul sold
= 6 u + 8
= 6 x 6 + 8
= 36 + 8
= 44
Answer(s): 44
