George and Cody had $1134 altogether. After George spent
16 of his money and Cody spent
56 of his money, George was left with twice as much money as Cody. How much money did Cody have at first?

| Before |
6x2 =
12 u |
6x5 =
30 u |
$1134 |
| Change |
- 1x2 =
- 2 u |
- 5x5 =
- 25 u |
|
| After |
5x2 =
10 u |
1x5 =
5 u |
|
Comparing George
and Cody in the end |
2x5 =
10 u |
1x5 =
5 u |
|
The amount that George had in the end is repeated. Make the amount that George had in the end the same. LCM of 5 and 2 is 10.
Total amount that George and Cody had at first
= 12 u + 30 u
= 42 u
42 u = 1134
1 u = 1134 ÷ 42 = 27
Amount that Cody had at first
= 30 u
= 30 x 27
= $810
Answer(s): $810
