Brandon and Perry had $560 altogether. After Brandon spent
14 of his money and Perry spent
78 of his money, Brandon was left with four times as much money as Perry. How much money did Perry have at first?

Total |
| Before |
4x4 =
16 u |
8x3 =
24 u |
$560 |
| Change |
- 1x4 =
- 4 u |
- 7x3 =
- 21 u |
|
| After |
3x4 =
12 u |
1x3 =
3 u |
|
Comparing Brandon
and Perry in the end |
4x3 =
12 u |
1x3 =
3 u |
|
The amount that Brandon had in the end is repeated. Make the amount that Brandon had in the end the same. LCM of 3 and 4 is 12.
Total amount that Brandon and Perry had at first
= 16 u + 24 u
= 40 u
40 u = 560
1 u = 560 ÷ 40 = 14
Amount that Perry had at first
= 24 u
= 24 x 14
= $336
Answer(s): $336
