20 u - 5 |
The number of cupcakes at first is repeated. Make the number of cupcakes at first the same. LCM of 3 and 5 is 15.
Total number of pastries left
= 6 u + 20 u - 5
= 26 u - 5
26 u - 5 = 229
26 u = 229 + 5
26 u = 234
1 u = 234 ÷ 26 = 9
Number of more cupcakes than scones that Charlie sold
= 9 u - 5
= 9 x 9 - 5
= 81 - 5
= 76
Answer(s): 76
