Irene and Rael had the same amount of savings at first. Then Irene spent
14 of her savings and Rael spent
23 of his savings. If Irene spent $1630 less than Rael, how much did each of them have at first?
| |
Irene |
Rael |
| Before |
4x3 =
12 u |
3x4 =
12 u |
| Change |
1x3 =
- 3 u |
2x4 =
- 8 u |
| After |
9 u |
4 u |
The amount that Irene and Rael had at first is the same. Make the amount that Irene and Rael each had the same. LCM of 4 and 3 is 12.
Amount that Irene spent less than Rael
= 8 u - 3 u
= 5 u
5 u = 1630
1 u = 1630 ÷ 5 = 326
Amount that each of them had at first
= 12 u
= 12 x 326
= $3912
Answer(s): $3912
