Rachel had an equal number of papayas and coconuts at first. She sold one-third of the coconuts and bought another 35 papayas. In the end, she had five times as many papayas as coconuts. Find the number of coconuts she had at first.

Coconuts |
Papayas |
| Before |
3 u |
10 u - 35 |
| Change |
- 1 u |
+ 35 |
| After |
2 u |
10 u |
The number of papayas and coconuts at first is the same.
10 u - 35 = 3 u
10 u - 3 u = 35
7 u = 35
1 u = 35 ÷ 7 = 5
Number of coconuts that she had at first
= 3 u
= 3 x 5
= 15
Answer(s): 15
