Natalie had an equal number of pomegranates and starfruits at first. She sold one-quarter of the starfruits and bought another 10 pomegranates. In the end, she had thrice as many pomegranates as starfruits. Find the number of starfruits she had at first.

Pomegranates |
Starfruits |
| Before |
9 u - 10 |
4 u |
| Change |
+ 10 |
- 1 u |
| After |
9 u |
3 u |
The number of pomegranates and starfruits at first is the same.
9 u - 10 = 4 u
9 u - 4 u = 10
5 u = 10
1 u = 10 ÷ 5 = 2
Number of starfruits that Natalie had at first
= 4 u
= 4 x 2
= 8
Answer(s): 8
