Vanessa had an equal number of grapefruits and papayas at first. She sold half of the papayas and bought another 99 grapefruits. In the end, she had five times as many grapefruits as papayas. Find the number of papayas she had at first.

Papayas |
Grapefruits |
| Before |
2 u |
5 u - 99 |
| Change |
- 1 u |
+ 99 |
| After |
1 u |
5 u |
The number of grapefruits and papayas at first is the same.
5 u - 99 = 2 u
5 u - 2 u = 99
3 u = 99
1 u = 99 ÷ 3 = 33
Number of papayas that she had at first
= 2 u
= 2 x 33
= 66
Answer(s): 66
