Julie and Xavier had the same amount of savings at first. Then Julie spent
14 of her savings and Xavier spent
45 of his savings. If Julie spent $1287 less than Xavier, how much did each of them have at first?

| Before |
4x5 =
20 u |
5x4 =
20 u |
| Change |
1x5 =
- 5 u |
4x4 =
- 16 u |
| After |
15 u |
4 u |
The amount that Julie and Xavier had at first is the same. Make the amount that Julie and Xavier each had the same. LCM of 4 and 5 is 20.
Amount that Julie spent less than Xavier
= 16 u - 5 u
= 11 u
11 u = 1287
1 u = 1287 ÷ 11 = 117
Amount that each of them had at first
= 20 u
= 20 x 117
= $2340
Answer(s): $2340
