Jane and Warren had a total of $149. After Jane spent
38 of her money and Warren spent $5, the ratio of Jane's money to Kennenth's money became 1 : 2. How much money had Warren at first?
| |
Jane |
Warren |
Total |
| Before |
8 u |
10 u + $5 |
$149 |
| Change |
- 3 u |
- $5 |
|
| After |
5 u |
|
|
Comparing Jane and
Warren in the end |
1x5 =
5 u |
2x5 =
10 u |
|
The amount that Jane had in the end is repeated. Make the amount that Jane had in the end the same. LCM of 5 and 1 is 5.
Total amount that Jane and Warren had at first
= 8 u + 10 u + 5
= 18 u + 5
18 u + 5 = 149
18 u = 149 - 5
18 u = 144
1 u = 144 ÷ 18 = 8
Amount that Warren had at first
= 10 u + 5
= 10 x 8 + 5
= 80 + 5
= $85
Answer(s): $85
