Nicole had 21 more caramel apples than Dylan at first. After Dylan had eaten 15 of his caramel apples, Nicole had 5 times as many caramel apples as Dylan. How many caramel apples did Nicole and Dylan have in total at first?

Dylan |
Total |
| Before |
1 u + 15 + 21 |
1 u + 15 |
6 u + 15 |
| Change |
|
- 15 |
|
| After |
5 u |
1 u |
|
The number of caramel apples that Nicole had at first remains unchanged.
5 u = 1 u + 15 + 21
5 u - 1 u = 36
4 u = 36
1 u = 36 ÷ 4 = 9
Number of caramel apples that they had at first
= 6 u + 15
= 6 x 9 + 15
= 54 + 15
= 69
Answer(s): 69
