David had 3 times as much money as Owen. After Owen's father gave Owen $40, the amount of money David had become $6 less than that of Owen's. How much did Owen have in the end?
| |
Owen |
David |
| Before |
1 u |
3 u |
| Change |
+ $40 |
|
| After |
1 u + $40 |
3 u |
The amount that David had remains unchanged.
If David had another $6, Owen and David would have the same amount in the end.
3 u + 6 = 1 u + 40
3 u - 1 u = 40 - 6
2 u = 40 - 6
2 u = 34
1 u = 34 ÷ 2 = 17
Amount that Owen had in the end
= 1 u + 40
= 17 + 40
= $57
Answer(s): $57
