Before |
6 u + 10 |
1 u + 50 |
Change |
- 10 |
- 50 |
After |
6 u |
1 u |
(a)
At first
Amount that Adam has = Amount that Bryan has
6 u + 10 = 1 u + 50
6 u - 1 u = 50 - 10
5 u = 40
1 u = 40 ÷ 5 = 8
Amount that each of them has at first
= 1 u + 50
= 8 + 50
= $58
(b)
Amount that Adam has more than Bryan in the end
= 6 u - 1 u
= 5 u
= 5 x 8
= $40
Answer(s): (a) $58; (b) $40
