Bryan and Rael had $624 altogether. After Bryan spent
16 of his money and Rael spent
23 of his money, Bryan was left with four times as much money as Rael. How much money did Rael have at first?

Total |
| Before |
6x4 =
24 u |
3x5 =
15 u |
$624 |
| Change |
- 1x4 =
- 4 u |
- 2x5 =
- 10 u |
|
| After |
5x4 =
20 u |
1x5 =
5 u |
|
Comparing Bryan
and Rael in the end |
4x5 =
20 u |
1x5 =
5 u |
|
The amount that Bryan had in the end is repeated. Make the amount that Bryan had in the end the same. LCM of 5 and 4 is 20.
Total amount that Bryan and Rael had at first
= 24 u + 15 u
= 39 u
39 u = 624
1 u = 624 ÷ 39 = 16
Amount that Rael had at first
= 15 u
= 15 x 16
= $240
Answer(s): $240
