Tom and Glen had $851 altogether. After Tom spent
14 of his money and Glen spent
67 of his money, Tom was left with four times as much money as Glen. How much money did Glen have at first?

4x4 =
16 u |
7x3 =
21 u |
$851 |
| Change |
- 1x4 =
- 4 u |
- 6x3 =
- 18 u |
|
| After |
3x4 =
12 u |
1x3 =
3 u |
|
Comparing Tom
and Glen in the end |
4x3 =
12 u |
1x3 =
3 u |
|
The amount that Tom had in the end is repeated. Make the amount that Tom had in the end the same. LCM of 3 and 4 is 12.
Total amount that Tom and Glen had at first
= 16 u + 21 u
= 37 u
37 u = 851
1 u = 851 ÷ 37 = 23
Amount that Glen had at first
= 21 u
= 21 x 23
= $483
Answer(s): $483
