Risa and Asher had a total of $43. After Risa spent
14 of her money and Asher spent $13, the ratio of Risa's money to Kennenth's money became 1 : 2. How much money had Asher at first?

Total |
| Before |
4 u |
6 u + $13 |
$43 |
| Change |
- 1 u |
- $13 |
|
| After |
3 u |
|

Comparing Risa and
Asher in the end |
1x3 =
3 u |
2x3 =
6 u |
|
The amount that Risa had in the end is repeated. Make the amount that Risa had in the end the same. LCM of 3 and 1 is 3.
Total amount that Risa and Asher had at first
= 4 u + 6 u + 13
= 10 u + 13
10 u + 13 = 43
10 u = 43 - 13
10 u = 30
1 u = 30 ÷ 10 = 3
Amount that Asher had at first
= 6 u + 13
= 6 x 3 + 13
= 18 + 13
= $31
Answer(s): $31
