Oscar and Daniel had $817 altogether. After Oscar spent
15 of his money and Daniel spent
67 of his money, Oscar was left with twice as much money as Daniel. How much money did Daniel have at first?

5x1 =
5 u |
7x2 =
14 u |
$817 |
| Change |
- 1x1 =
- 1 u |
- 6x2 =
- 12 u |
|
| After |
4x1 =
4 u |
1x2 =
2 u |
|
Comparing Oscar
and Daniel in the end |
2x2 =
4 u |
1x2 =
2 u |
|
The amount that Oscar had in the end is repeated. Make the amount that Oscar had in the end the same. LCM of 4 and 2 is 4.
Total amount that Oscar and Daniel had at first
= 5 u + 14 u
= 19 u
19 u = 817
1 u = 817 ÷ 19 = 43
Amount that Daniel had at first
= 14 u
= 14 x 43
= $602
Answer(s): $602
