Before |
5 u + 10 |
1 u + 50 |
Change |
- 10 |
- 50 |
After |
5 u |
1 u |
(a)
At first
Amount that Bryan has = Amount that Adam has
5 u + 10 = 1 u + 50
5 u - 1 u = 50 - 10
4 u = 40
1 u = 40 ÷ 4 = 10
Amount that each of them has at first
= 1 u + 50
= 10 + 50
= $60
(b)
Amount that Bryan has more than Adam in the end
= 5 u - 1 u
= 4 u
= 4 x 10
= $40
Answer(s): (a) $60; (b) $40
