Gabby and Warren had a total of $161. After Gabby spent
16 of her money and Warren spent $6, the ratio of Gabby's money to Kennenth's money became 1 : 5. How much money had Warren at first?

Gabby |
Warren |
Total |
| Before |
6 u |
25 u + $6 |
$161 |
| Change |
- 1 u |
- $6 |
|
| After |
5 u |
|
|
Comparing Gabby and
Warren in the end |
1x5 =
5 u |
5x5 =
25 u |
|
The amount that Gabby had in the end is repeated. Make the amount that Gabby had in the end the same. LCM of 5 and 1 is 5.
Total amount that Gabby and Warren had at first
= 6 u + 25 u + 6
= 31 u + 6
31 u + 6 = 161
31 u = 161 - 6
31 u = 155
1 u = 155 ÷ 31 = 5
Amount that Warren had at first
= 25 u + 6
= 25 x 5 + 6
= 125 + 6
= $131
Answer(s): $131
