Albert and John had $425 altogether. After Albert spent
14 of his money and John spent
23 of his money, Albert was left with four times as much money as John. How much money did John have at first?

$425 |
| Change |
- 1x4 =
- 4 u |
- 2x3 =
- 6 u |
|
| After |
3x4 =
12 u |
1x3 =
3 u |
|
Comparing Albert
and John in the end |
4x3 =
12 u |
1x3 =
3 u |
|
The amount that Albert had in the end is repeated. Make the amount that Albert had in the end the same. LCM of 3 and 4 is 12.
Total amount that Albert and John had at first
= 16 u + 9 u
= 25 u
25 u = 425
1 u = 425 ÷ 25 = 17
Amount that John had at first
= 9 u
= 9 x 17
= $153
Answer(s): $153
