Before |
3 u - 60 |
1 u - 10 |
Change |
+ 60 |
+ 10 |
After |
3 u |
1 u |
(a)
At first
Amount that Alan has = Amount that Brent has
3 u - 60 = 1 u - 10
3 u - 1 u = 60 - 10
2 u = 50
1 u = 50 ÷ 2 = 25
Amount that each of them has at first
= 1 u - 10
= 25 - 10
= $15
(b)
Amount that Brent has less than Alan in the end
= 3 u - 1 u
= 2 u
= 2 x 25
= $50
Answer(s): (a) $15; (b) $50
