Jaslyn and Daniel had a total of $55. After Jaslyn spent
15 of her money and Daniel spent $4, the ratio of Jaslyn's money to Kennenth's money became 1 : 3. How much money had Daniel at first?

Total |
| Before |
5 u |
12 u + $4 |
$55 |
| Change |
- 1 u |
- $4 |
|
| After |
4 u |
|
|
Comparing Jaslyn and
Daniel in the end |
1x4 =
4 u |
3x4 =
12 u |
|
The amount that Jaslyn had in the end is repeated. Make the amount that Jaslyn had in the end the same. LCM of 4 and 1 is 4.
Total amount that Jaslyn and Daniel had at first
= 5 u + 12 u + 4
= 17 u + 4
17 u + 4 = 55
17 u = 55 - 4
17 u = 51
1 u = 51 ÷ 17 = 3
Amount that Daniel had at first
= 12 u + 4
= 12 x 3 + 4
= 36 + 4
= $40
Answer(s): $40
