Joelle and Julian had the same amount of savings at first. Then Joelle spent
15 of her savings and Julian spent
34 of his savings. If Joelle spent $792 less than Julian, how much did each of them have at first?

Joelle |
Julian |
| Before |
5x4 =
20 u |
4x5 =
20 u |
| Change |
1x4 =
- 4 u |
3x5 =
- 15 u |
| After |
16 u |
5 u |
The amount that Joelle and Julian had at first is the same. Make the amount that Joelle and Julian each had the same. LCM of 5 and 4 is 20.
Amount that Joelle spent less than Julian
= 15 u - 4 u
= 11 u
11 u = 792
1 u = 792 ÷ 11 = 72
Amount that each of them had at first
= 20 u
= 20 x 72
= $1440
Answer(s): $1440
