Sabrina and Owen had a total of $194. After Sabrina spent
38 of her money and Owen spent $10, the ratio of Sabrina's money to Kennenth's money became 1 : 3. How much money had Owen at first?

Total |
| Before |
8 u |
15 u + $10 |
$194 |
| Change |
- 3 u |
- $10 |
|
| After |
5 u |
|

Comparing Sabrina and
Owen in the end |
1x5 =
5 u |
3x5 =
15 u |
|
The amount that Sabrina had in the end is repeated. Make the amount that Sabrina had in the end the same. LCM of 5 and 1 is 5.
Total amount that Sabrina and Owen had at first
= 8 u + 15 u + 10
= 23 u + 10
23 u + 10 = 194
23 u = 194 - 10
23 u = 184
1 u = 184 ÷ 23 = 8
Amount that Owen had at first
= 15 u + 10
= 15 x 8 + 10
= 120 + 10
= $130
Answer(s): $130
