Dylan and Perry had $430 altogether. After Dylan spent
16 of his money and Perry spent
45 of his money, Dylan was left with thrice as much money as Perry. How much money did Perry have at first?

| Before |
6x3 =
18 u |
5x5 =
25 u |
$430 |
| Change |
- 1x3 =
- 3 u |
- 4x5 =
- 20 u |
|
| After |
5x3 =
15 u |
1x5 =
5 u |
|
Comparing Dylan
and Perry in the end |
3x5 =
15 u |
1x5 =
5 u |
|
The amount that Dylan had in the end is repeated. Make the amount that Dylan had in the end the same. LCM of 5 and 3 is 15.
Total amount that Dylan and Perry had at first
= 18 u + 25 u
= 43 u
43 u = 430
1 u = 430 ÷ 43 = 10
Amount that Perry had at first
= 25 u
= 25 x 10
= $250
Answer(s): $250
