Will and Jeremy had $1161 altogether. After Will spent
16 of his money and Jeremy spent
23 of his money, Will was left with twice as much money as Jeremy. How much money did Jeremy have at first?

6x2 =
12 u |
3x5 =
15 u |
$1161 |
| Change |
- 1x2 =
- 2 u |
- 2x5 =
- 10 u |
|
| After |
5x2 =
10 u |
1x5 =
5 u |
|
Comparing Will
and Jeremy in the end |
2x5 =
10 u |
1x5 =
5 u |
|
The amount that Will had in the end is repeated. Make the amount that Will had in the end the same. LCM of 5 and 2 is 10.
Total amount that Will and Jeremy had at first
= 12 u + 15 u
= 27 u
27 u = 1161
1 u = 1161 ÷ 27 = 43
Amount that Jeremy had at first
= 15 u
= 15 x 43
= $645
Answer(s): $645
