Before |
6 u + 10 |
1 u + 80 |
Change |
- 10 |
- 80 |
After |
6 u |
1 u |
(a)
At first
Amount that Bryan has = Amount that Adam has
6 u + 10 = 1 u + 80
6 u - 1 u = 80 - 10
5 u = 70
1 u = 70 ÷ 5 = 14
Amount that each of them has at first
= 1 u + 80
= 14 + 80
= $94
(b)
Amount that Bryan has more than Adam in the end
= 6 u - 1 u
= 5 u
= 5 x 14
= $70
Answer(s): (a) $94; (b) $70
