Jeremy and Oscar had $368 altogether. After Jeremy spent
13 of his money and Oscar spent
67 of his money, Jeremy was left with thrice as much money as Oscar. How much money did Oscar have at first?

| Before |
3x3 =
9 u |
7x2 =
14 u |
$368 |
| Change |
- 1x3 =
- 3 u |
- 6x2 =
- 12 u |
|
| After |
2x3 =
6 u |
1x2 =
2 u |
|
Comparing Jeremy
and Oscar in the end |
3x2 =
6 u |
1x2 =
2 u |
|
The amount that Jeremy had in the end is repeated. Make the amount that Jeremy had in the end the same. LCM of 2 and 3 is 6.
Total amount that Jeremy and Oscar had at first
= 9 u + 14 u
= 23 u
23 u = 368
1 u = 368 ÷ 23 = 16
Amount that Oscar had at first
= 14 u
= 14 x 16
= $224
Answer(s): $224
