Jade had an equal number of coconuts and peaches at first. She sold two-thirds of the peaches and bought another 72 coconuts. In the end, she had five times as many coconuts as peaches. Find the number of peaches she had at first.

Peaches |
Coconuts |
| Before |
3 u |
5 u - 72 |
| Change |
- 2 u |
+ 72 |
| After |
1 u |
5 u |
The number of coconuts and peaches at first is the same.
5 u - 72 = 3 u
5 u - 3 u = 72
2 u = 72
1 u = 72 ÷ 2 = 36
Number of peaches that she had at first
= 3 u
= 3 x 36
= 108
Answer(s): 108
