1x1 =

10 u - 2 |
The number of cupcakes at first is repeated. Make the number of cupcakes at first the same. LCM of 2 and 4 is 4.
Total number of pastries left
= 1 u + 10 u - 2
= 11 u - 2
11 u - 2 = 75
11 u = 75 + 2
11 u = 77
1 u = 77 ÷ 11 = 7
Number of more cupcakes than muffins that Cole sold
= 3 u - 2
= 3 x 7 - 2
= 21 - 2
= 19
Answer(s): 19
