Before |
6 u + 40 |
1 u + 80 |
Change |
- 40 |
- 80 |
After |
6 u |
1 u |
(a)
At first
Amount that Charlie has = Amount that Bryan has
6 u + 40 = 1 u + 80
6 u - 1 u = 80 - 40
5 u = 40
1 u = 40 ÷ 5 = 8
Amount that each of them has at first
= 1 u + 80
= 8 + 80
= $88
(b)
Amount that Bryan has less than Charlie in the end
= 6 u - 1 u
= 5 u
= 5 x 8
= $40
Answer(s): (a) $88; (b) $40
