Cindy and Ethan had the same amount of savings at first. Then Cindy spent
16 of her savings and Ethan spent
34 of his savings. If Cindy spent $798 less than Ethan, how much did each of them have at first?

Cindy |
Ethan |
| Before |
6x2 =
12 u |
4x3 =
12 u |
| Change |
1x2 =
- 2 u |
3x3 =
- 9 u |
| After |
10 u |
3 u |
The amount that Cindy and Ethan had at first is the same. Make the amount that Cindy and Ethan each had the same. LCM of 6 and 4 is 12.
Amount that Cindy spent less than Ethan
= 9 u - 2 u
= 7 u
7 u = 798
1 u = 798 ÷ 7 = 114
Amount that each of them had at first
= 12 u
= 12 x 114
= $1368
Answer(s): $1368
