Xuan and Ahmad had the same amount of savings at first. Then Xuan spent
15 of her savings and Ahmad spent
34 of his savings. If Xuan spent $1584 less than Ahmad, how much did each of them have at first?
|
Xuan |
Ahmad |
Before |
5x4 = 20 u |
4x5 = 20 u |
Change |
1x4 = - 4 u |
3x5 = - 15 u |
After |
16 u |
5 u |
The amount that Xuan and Ahmad had at first is the same. Make the amount that Xuan and Ahmad each had the same. LCM of 5 and 4 is 20.
Amount that Xuan spent less than Ahmad
= 15 u - 4 u
= 11 u
11 u = 1584
1 u = 1584 ÷ 11 = 144
Amount that each of them had at first
= 20 u
= 20 x 144
= $2880
Answer(s): $2880
