Cindy and Xavier had the same amount of savings at first. Then Cindy spent
17 of her savings and Xavier spent
23 of his savings. If Cindy spent $1397 less than Xavier, how much did each of them have at first?

| Before |
7x3 =
21 u |
3x7 =
21 u |
| Change |
1x3 =
- 3 u |
2x7 =
- 14 u |
| After |
18 u |
7 u |
The amount that Cindy and Xavier had at first is the same. Make the amount that Cindy and Xavier each had the same. LCM of 7 and 3 is 21.
Amount that Cindy spent less than Xavier
= 14 u - 3 u
= 11 u
11 u = 1397
1 u = 1397 ÷ 11 = 127
Amount that each of them had at first
= 21 u
= 21 x 127
= $2667
Answer(s): $2667
