Gabby had an equal number of peaches and mangosteens at first. She sold one-quarter of the mangosteens and bought another 76 peaches. In the end, she had twice as many peaches as mangosteens. Find the number of mangosteens she had at first.

Mangosteens |
Peaches |
| Before |
4 u |
6 u - 76 |
| Change |
- 1 u |
+ 76 |
| After |
3 u |
6 u |
The number of peaches and mangosteens at first is the same.
6 u - 76 = 4 u
6 u - 4 u = 76
2 u = 76
1 u = 76 ÷ 2 = 38
Number of mangosteens that she had at first
= 4 u
= 4 x 38
= 152
Answer(s): 152
