15 u - 8 |
The number of cupcakes at first is repeated. Make the number of cupcakes at first the same. LCM of 4 and 5 is 20.
Total number of pastries left
= 8 u + 15 u - 8
= 23 u - 8
23 u - 8 = 84
23 u = 84 + 8
23 u = 92
1 u = 92 ÷ 23 = 4
Number of more cupcakes than scones that Albert sold
= 12 u - 8
= 12 x 4 - 8
= 48 - 8
= 40
Answer(s): 40
