$850 more |
| Before |
1 u + $370 |
5 u |
| Change |
- $370 |
|
| After |
1 u |
5 u |
After
Amount that Mr Neo has = 1 u
Amount that Mr Oh has = 5 x 1 u = 5 u
Before
Amount that Mr Neo has = 1 u + 370
Amount that Mr Oh has = 5 u
Mr Oh had $850 more than Mr Neo at first.
If another $850 is given to Mr Neo at first, both will have the same amount at first.
5 u = 1 u + 370 + 850
5 u = 1 u + 1220
5 u - 1 u = 1220
4 u = 1220
1 u = 1220 ÷ 4 = 305
Amount that Mr Neo had at first
= 1 u + 370
= 305 + 370
= $675
Answer(s): $675
