Marion and Cody had the same amount of savings at first. Then Marion spent
16 of her savings and Cody spent
34 of his savings. If Marion spent $1610 less than Cody, how much did each of them have at first?

Marion |
Cody |
| Before |
6x2 =
12 u |
4x3 =
12 u |
| Change |
1x2 =
- 2 u |
3x3 =
- 9 u |
| After |
10 u |
3 u |
The amount that Marion and Cody had at first is the same. Make the amount that Marion and Cody each had the same. LCM of 6 and 4 is 12.
Amount that Marion spent less than Cody
= 9 u - 2 u
= 7 u
7 u = 1610
1 u = 1610 ÷ 7 = 230
Amount that each of them had at first
= 12 u
= 12 x 230
= $2760
Answer(s): $2760
