Jade and Julian had the same amount of savings at first. Then Jade spent
17 of her savings and Julian spent
23 of his savings. If Jade spent $1430 less than Julian, how much did each of them have at first?

Jade |
Julian |
| Before |
7x3 =
21 u |
3x7 =
21 u |
| Change |
1x3 =
- 3 u |
2x7 =
- 14 u |
| After |
18 u |
7 u |
The amount that Jade and Julian had at first is the same. Make the amount that Jade and Julian each had the same. LCM of 7 and 3 is 21.
Amount that Jade spent less than Julian
= 14 u - 3 u
= 11 u
11 u = 1430
1 u = 1430 ÷ 11 = 130
Amount that each of them had at first
= 21 u
= 21 x 130
= $2730
Answer(s): $2730
