Before |
3 u - 90 |
1 u - 10 |
Change |
+ 90 |
+ 10 |
After |
3 u |
1 u |
(a)
At first
Amount that Aqil has = Amount that Baxter has
3 u - 90 = 1 u - 10
3 u - 1 u = 90 - 10
2 u = 80
1 u = 80 ÷ 2 = 40
Amount that each of them has at first
= 1 u - 10
= 40 - 10
= $30
(b)
Amount that Baxter has less than Aqil in the end
= 3 u - 1 u
= 2 u
= 2 x 40
= $80
Answer(s): (a) $30; (b) $80
