| Change |
- $349 |
|
| After |
1 u |
3 u |
After
Amount that Mr Fong has = 1 u
Amount that Mr Chan has = 3 x 1 u = 3 u
Before
Amount that Mr Fong has = 1 u + 349
Amount that Mr Chan has = 3 u
Mr Chan had $777 more than Mr Fong at first.
If another $777 is given to Mr Fong at first, both will have the same amount at first.
3 u = 1 u + 349 + 777
3 u = 1 u + 1126
3 u - 1 u = 1126
2 u = 1126
1 u = 1126 ÷ 2 = 563
Amount that Mr Fong had at first
= 1 u + 349
= 563 + 349
= $912
Answer(s): $912
