18 u - 20 |
The number of muffins at first is repeated. Make the number of muffins at first the same. LCM of 5 and 6 is 30.
Total number of pastries left
= 5 u + 18 u - 20
= 23 u - 20
23 u - 20 = 118
23 u = 118 + 20
23 u = 138
1 u = 138 ÷ 23 = 6
Number of more muffins than wafers that Jenson sold
= 25 u - 20
= 25 x 6 - 20
= 150 - 20
= 130
Answer(s): 130
