Adam |
Before |
6 u + 40 |
1 u + 90 |
Change |
- 40 |
- 90 |
After |
6 u |
1 u |
(a)
At first
Amount that Bryan has = Amount that Adam has
6 u + 40 = 1 u + 90
6 u - 1 u = 90 - 40
5 u = 50
1 u = 50 ÷ 5 = 10
Amount that each of them has at first
= 1 u + 90
= 10 + 90
= $100
(b)
Amount that Bryan has more than Adam in the end
= 6 u - 1 u
= 5 u
= 5 x 10
= $50
Answer(s): (a) $100; (b) $50
