Glen and Eric had $483 altogether. After Glen spent
13 of his money and Eric spent
23 of his money, Glen was left with five times as much money as Eric. How much money did Eric have at first?

$483 |
| Change |
- 1x5 =
- 5 u |
- 2x2 =
- 4 u |
|
| After |
2x5 =
10 u |
1x2 =
2 u |
|
Comparing Glen
and Eric in the end |
5x2 =
10 u |
1x2 =
2 u |
|
The amount that Glen had in the end is repeated. Make the amount that Glen had in the end the same. LCM of 2 and 5 is 10.
Total amount that Glen and Eric had at first
= 15 u + 6 u
= 21 u
21 u = 483
1 u = 483 ÷ 21 = 23
Amount that Eric had at first
= 6 u
= 6 x 23
= $138
Answer(s): $138
