Before |
5 u + 60 |
1 u + 80 |
Change |
- 60 |
- 80 |
After |
5 u |
1 u |
(a)
At first
Amount that Bryan has = Amount that Adam has
5 u + 60 = 1 u + 80
5 u - 1 u = 80 - 60
4 u = 20
1 u = 20 ÷ 4 = 5
Amount that each of them has at first
= 1 u + 80
= 5 + 80
= $85
(b)
Amount that Adam has less than Bryan in the end
= 5 u - 1 u
= 4 u
= 4 x 5
= $20
Answer(s): (a) $85; (b) $20
