Joelle and Elijah had the same amount of savings at first. Then Joelle spent
14 of her savings and Elijah spent
45 of his savings. If Joelle spent $836 less than Elijah, 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 Joelle and Elijah had at first is the same. Make the amount that Joelle and Elijah each had the same. LCM of 4 and 5 is 20.
Amount that Joelle spent less than Elijah
= 16 u - 5 u
= 11 u
11 u = 836
1 u = 836 ÷ 11 = 76
Amount that each of them had at first
= 20 u
= 20 x 76
= $1520
Answer(s): $1520
