Owen and Andy had $703 altogether. After Owen spent
16 of his money and Andy spent
45 of his money, Owen was left with twice as much money as Andy. How much money did Andy have at first?

Total |
| Before |
6x2 =
12 u |
5x5 =
25 u |
$703 |
| Change |
- 1x2 =
- 2 u |
- 4x5 =
- 20 u |
|
| After |
5x2 =
10 u |
1x5 =
5 u |
|
Comparing Owen
and Andy in the end |
2x5 =
10 u |
1x5 =
5 u |
|
The amount that Owen had in the end is repeated. Make the amount that Owen had in the end the same. LCM of 5 and 2 is 10.
Total amount that Owen and Andy had at first
= 12 u + 25 u
= 37 u
37 u = 703
1 u = 703 ÷ 37 = 19
Amount that Andy had at first
= 25 u
= 25 x 19
= $475
Answer(s): $475
