Before |
5 u - 70 |
1 u - 10 |
Change |
+ 70 |
+ 10 |
After |
5 u |
1 u |
(a)
At first
Amount that Alex has = Amount that Bradley has
5 u - 70 = 1 u - 10
5 u - 1 u = 70 - 10
4 u = 60
1 u = 60 ÷ 4 = 15
Amount that each of them has at first
= 1 u - 10
= 15 - 10
= $5
(b)
Amount that Bradley has less than Alex in the end
= 5 u - 1 u
= 4 u
= 4 x 15
= $60
Answer(s): (a) $5; (b) $60
