Before |
6 u + 40 |
1 u + 50 |
Change |
- 40 |
- 50 |
After |
6 u |
1 u |
(a)
At first
Amount that Adam has = Amount that Bryan has
6 u + 40 = 1 u + 50
6 u - 1 u = 50 - 40
5 u = 10
1 u = 10 ÷ 5 = 2
Amount that each of them has at first
= 1 u + 50
= 2 + 50
= $52
(b)
Amount that Bryan has less than Adam in the end
= 6 u - 1 u
= 5 u
= 5 x 2
= $10
Answer(s): (a) $52; (b) $10
