Gabby had 29 more mini cupcakes than Eric at first. After Eric had eaten 15 of his mini cupcakes, Gabby had 5 times as many mini cupcakes as Eric. How many mini cupcakes did Gabby and Eric have in total at first?

Total |
| Before |
1 u + 15 + 29 |
1 u + 15 |
6 u + 15 |
| Change |
|
- 15 |
|
| After |
5 u |
1 u |
|
The number of mini cupcakes that Gabby had at first remains unchanged.
5 u = 1 u + 15 + 29
5 u - 1 u = 44
4 u = 44
1 u = 44 ÷ 4 = 11
Number of mini cupcakes that they had at first
= 6 u + 15
= 6 x 11 + 15
= 66 + 15
= 81
Answer(s): 81
