Tammy had an equal number of peaches and guavas at first. She sold two-thirds of the guavas and bought another 100 peaches. In the end, she had five times as many peaches as guavas. Find the number of guavas she had at first.

Guavas |
Peaches |
| Before |
3 u |
5 u - 100 |
| Change |
- 2 u |
+ 100 |
| After |
1 u |
5 u |
The number of peaches and guavas at first is the same.
5 u - 100 = 3 u
5 u - 3 u = 100
2 u = 100
1 u = 100 ÷ 2 = 50
Number of guavas that she had at first
= 3 u
= 3 x 50
= 150
Answer(s): 150
