Tina had an equal number of pears and pomegranates at first. She sold half of the pomegranates and bought another 68 pears. In the end, she had four times as many pears as pomegranates. Find the number of pomegranates she had at first.

Pomegranates |
Pears |
| Before |
2 u |
4 u - 68 |
| Change |
- 1 u |
+ 68 |
| After |
1 u |
4 u |
The number of pears and pomegranates at first is the same.
4 u - 68 = 2 u
4 u - 2 u = 68
2 u = 68
1 u = 68 ÷ 2 = 34
Number of pomegranates that she had at first
= 2 u
= 2 x 34
= 68
Answer(s): 68
