13 of his money and Charlie spent
23 of his money, Flynn was left with thrice as much money as Charlie. How much money did Charlie have at first?

$720 |
| Change |
- 1x3 =
- 3 u |
- 2x2 =
- 4 u |
|
| After |
2x3 =
6 u |
1x2 =
2 u |
|
Comparing Flynn
and Charlie in the end |
3x2 =
6 u |
1x2 =
2 u |
|
The amount that Flynn had in the end is repeated. Make the amount that Flynn had in the end the same. LCM of 2 and 3 is 6.
Total amount that Flynn and Charlie had at first
= 9 u + 6 u
= 15 u
15 u = 720
1 u = 720 ÷ 15 = 48
Amount that Charlie had at first
= 6 u
= 6 x 48
= $288
Answer(s): $288
