Pamela had 15 more mini cupcakes than Will at first. After Will had eaten 25 of his mini cupcakes, Pamela had 5 times as many mini cupcakes as Will. How many mini cupcakes did Pamela and Will have in total at first?

Will |
Total |
| Before |
1 u + 25 + 15 |
1 u + 25 |
6 u + 25 |
| Change |
|
- 25 |
|
| After |
5 u |
1 u |
|
The number of mini cupcakes that Pamela had at first remains unchanged.
5 u = 1 u + 25 + 15
5 u - 1 u = 40
4 u = 40
1 u = 40 ÷ 4 = 10
Number of mini cupcakes that they had at first
= 6 u + 25
= 6 x 10 + 25
= 60 + 25
= 85
Answer(s): 85
