Before |
6 u + 60 |
1 u + 80 |
Change |
- 60 |
- 80 |
After |
6 u |
1 u |
(a)
At first
Amount that Adam has = Amount that Bryan has
6 u + 60 = 1 u + 80
6 u - 1 u = 80 - 60
5 u = 20
1 u = 20 ÷ 5 = 4
Amount that each of them has at first
= 1 u + 80
= 4 + 80
= $84
(b)
Amount that Bryan has less than Adam in the end
= 6 u - 1 u
= 5 u
= 5 x 4
= $20
Answer(s): (a) $84; (b) $20
