Opal and Glen had a total of $197. After Opal spent
58 of her money and Glen spent $15, the ratio of Opal's money to Kennenth's money became 1 : 6. How much money had Glen at first?

Total |
| Before |
8 u |
18 u + $15 |
$197 |
| Change |
- 5 u |
- $15 |
|
| After |
3 u |

Comparing Opal and
Glen in the end |
1x3 =
3 u |
6x3 =
18 u |
|
The amount that Opal had in the end is repeated. Make the amount that Opal had in the end the same. LCM of 3 and 1 is 3.
Total amount that Opal and Glen had at first
= 8 u + 18 u + 15
= 26 u + 15
26 u + 15 = 197
26 u = 197 - 15
26 u = 182
1 u = 182 ÷ 26 = 7
Amount that Glen had at first
= 18 u + 15
= 18 x 7 + 15
= 126 + 15
= $141
Answer(s): $141
