Risa had an equal number of apricots and tomatoes at first. She sold one-third of the tomatoes and bought another 49 apricots. In the end, she had five times as many apricots as tomatoes. Find the number of tomatoes she had at first.

Tomatoes |
Apricots |
| Before |
3 u |
10 u - 49 |
| Change |
- 1 u |
+ 49 |
| After |
2 u |
10 u |
The number of apricots and tomatoes at first is the same.
10 u - 49 = 3 u
10 u - 3 u = 49
7 u = 49
1 u = 49 ÷ 7 = 7
Number of tomatoes that she had at first
= 3 u
= 3 x 7
= 21
Answer(s): 21
