Roshel and Tommy had a total of $194. After Roshel spent
38 of her money and Tommy spent $4, the ratio of Roshel's money to Kennenth's money became 1 : 6. How much money had Tommy at first?

Total |
| Before |
8 u |
30 u + $4 |
$194 |
| Change |
- 3 u |
- $4 |
|
| After |
5 u |
|
|
Comparing Roshel and
Tommy in the end |
1x5 =
5 u |
6x5 =
30 u |
|
The amount that Roshel had in the end is repeated. Make the amount that Roshel had in the end the same. LCM of 5 and 1 is 5.
Total amount that Roshel and Tommy had at first
= 8 u + 30 u + 4
= 38 u + 4
38 u + 4 = 194
38 u = 194 - 4
38 u = 190
1 u = 190 ÷ 38 = 5
Amount that Tommy had at first
= 30 u + 4
= 30 x 5 + 4
= 150 + 4
= $154
Answer(s): $154
