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

Pears |

| Before |
2 u |
5 u - 78 |
| Change |
- 1 u |
+ 78 |
| After |
1 u |
5 u |
The number of peaches and pears 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 pears that she had at first
= 2 u
= 2 x 26
= 52
Answer(s): 52
