Zoe had an equal number of kiwis and peaches at first. She sold one-fifth of the peaches and bought another 30 kiwis. In the end, she had five times as many kiwis as peaches. Find the number of peaches she had at first.

Kiwis |
Peaches |
| Before |
20 u - 30 |
5 u |
| Change |
+ 30 |
- 1 u |
| After |
20 u |
4 u |
The number of kiwis and peaches at first is the same.
20 u - 30 = 5 u
20 u - 5 u = 30
15 u = 30
1 u = 30 ÷ 15 = 2
Number of peaches that Zoe had at first
= 5 u
= 5 x 2
= 10
Answer(s): 10
