Zoe had an equal number of mangosteens and peaches at first. She sold one-quarter of the peaches and bought another 96 mangosteens. In the end, she had twice as many mangosteens as peaches. Find the number of peaches she had at first.

Peaches |
Mangosteens |
| Before |
4 u |
6 u - 96 |
| Change |
- 1 u |
+ 96 |
| After |
3 u |
6 u |
The number of mangosteens and peaches at first is the same.
6 u - 96 = 4 u
6 u - 4 u = 96
2 u = 96
1 u = 96 ÷ 2 = 48
Number of peaches that she had at first
= 4 u
= 4 x 48
= 192
Answer(s): 192
