15 u - 8 |
The number of tarts at first is repeated. Make the number of tarts at first the same. LCM of 4 and 5 is 20.
Total number of pastries left
= 12 u + 15 u - 8
= 27 u - 8
27 u - 8 = 127
27 u = 127 + 8
27 u = 135
1 u = 135 ÷ 27 = 5
Number of more tarts than scones that Perry sold
= 8 u - 8
= 8 x 5 - 8
= 40 - 8
= 32
Answer(s): 32
