Fiona had an equal number of lemons and peaches at first. She sold half of the peaches and bought another 78 lemons. In the end, she had five times as many lemons as peaches. Find the number of peaches she had at first.

Peaches |
Lemons |
| Before |
2 u |
5 u - 78 |
| Change |
- 1 u |
+ 78 |
| After |
1 u |
5 u |
The number of lemons and peaches at first is the same.
5 u - 78 = 2 u
5 u - 2 u = 78
3 u = 78
1 u = 78 ÷ 3 = 26
Number of peaches that she had at first
= 2 u
= 2 x 26
= 52
Answer(s): 52
