10 u - 10 |
The number of scones at first is repeated. Make the number of scones at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 10 u - 10
= 11 u - 10
11 u - 10 = 45
11 u = 45 + 10
11 u = 55
1 u = 55 ÷ 11 = 5
Number of more scones than cupcakes that Charlie sold
= 5 u - 10
= 5 x 5 - 10
= 25 - 10
= 15
Answer(s): 15
