- 3 u |
- 48 |
| After |
1 u |

| Comparing between Eva and Roshel in the end |
1 u |
4 u |
Total amount that Eva and Roshel had at first
= 4 u + 4 u + 48
= 8 u + 48
8 u + 48 = 384
4 u + 3 u = 384 - 48
8 u = 336
1 u = 336 ÷ 8 = 42
Amount that Eva had at first
= 4 u
= 4 x 42
= $168
Amount that Roshel had at first
= 384 - 168
= $216
At first
Eva : Roshel
168 : 216
7 : 9
Answer(s): 7 : 9
