Jade had an equal number of limes and coconuts at first. She sold half of the coconuts and bought another 72 limes. In the end, she had four times as many limes as coconuts. Find the number of coconuts she had at first.

Coconuts |
Limes |
| Before |
2 u |
4 u - 72 |
| Change |
- 1 u |
+ 72 |
| After |
1 u |
4 u |
The number of limes and coconuts at first is the same.
4 u - 72 = 2 u
4 u - 2 u = 72
2 u = 72
1 u = 72 ÷ 2 = 36
Number of coconuts that she had at first
= 2 u
= 2 x 36
= 72
Answer(s): 72
