15 of his money and Will spent
67 of his money, George was left with five times as much money as Will. How much money did Will have at first?

| Change |
- 1x5 =
- 5 u |
- 6x4 =
- 24 u |
|
| After |
4x5 =
20 u |
1x4 =
4 u |
|
Comparing George
and Will in the end |
5x4 =
20 u |
1x4 =
4 u |
|
The amount that George had in the end is repeated. Make the amount that George had in the end the same. LCM of 4 and 5 is 20.
Total amount that George and Will had at first
= 25 u + 28 u
= 53 u
53 u = 1749
1 u = 1749 ÷ 53 = 33
Amount that Will had at first
= 28 u
= 28 x 33
= $924
Answer(s): $924
