Shiyun had an equal number of papayas and tomatoes at first. She sold half of the tomatoes and bought another 87 papayas. In the end, she had five times as many papayas as tomatoes. Find the number of tomatoes she had at first.

Tomatoes |
Papayas |
| Before |
2 u |
5 u - 87 |
| Change |
- 1 u |
+ 87 |
| After |
1 u |
5 u |
The number of papayas and tomatoes at first is the same.
5 u - 87 = 2 u
5 u - 2 u = 87
3 u = 87
1 u = 87 ÷ 3 = 29
Number of tomatoes that she had at first
= 2 u
= 2 x 29
= 58
Answer(s): 58
