Jaslyn had an equal number of grapefruits and mangoes at first. She sold half of the mangoes and bought another 27 grapefruits. In the end, she had five times as many grapefruits as mangoes. Find the number of mangoes she had at first.

Grapefruits |
Mangoes |
| Before |
5 u - 27 |
2 u |
| Change |
+ 27 |
- 1 u |
| After |
5 u |
1 u |
The number of grapefruits and mangoes at first is the same.
5 u - 27 = 2 u
5 u - 2 u = 27
3 u = 27
1 u = 27 ÷ 3 = 9
Number of mangoes that Jaslyn had at first
= 2 u
= 2 x 9
= 18
Answer(s): 18
