Marion had an equal number of peaches and dragonfruits at first. She sold one-quarter of the dragonfruits and bought another 16 peaches. In the end, she had four times as many peaches as dragonfruits. Find the number of dragonfruits she had at first.

Peaches |
Dragonfruits |
| Before |
12 u - 16 |
4 u |
| Change |
+ 16 |
- 1 u |
| After |
12 u |
3 u |
The number of peaches and dragonfruits at first is the same.
12 u - 16 = 4 u
12 u - 4 u = 16
8 u = 16
1 u = 16 ÷ 8 = 2
Number of dragonfruits that Marion had at first
= 4 u
= 4 x 2
= 8
Answer(s): 8
