Irene and Archie had the same amount of savings at first. Then Irene spent
14 of her savings and Archie spent
56 of his savings. If Irene spent $560 less than Archie, how much did each of them have at first?
| |
Irene |
Archie |
| Before |
4x3 =
12 u |
6x2 =
12 u |
| Change |
1x3 =
- 3 u |
5x2 =
- 10 u |
| After |
9 u |
2 u |
The amount that Irene and Archie had at first is the same. Make the amount that Irene and Archie each had the same. LCM of 4 and 6 is 12.
Amount that Irene spent less than Archie
= 10 u - 3 u
= 7 u
7 u = 560
1 u = 560 ÷ 7 = 80
Amount that each of them had at first
= 12 u
= 12 x 80
= $960
Answer(s): $960
