Before |
6 u + 70 |
1 u + 100 |
Change |
- 70 |
- 100 |
After |
6 u |
1 u |
(a)
At first
Amount that Charlie has = Amount that Bryan has
6 u + 70 = 1 u + 100
6 u - 1 u = 100 - 70
5 u = 30
1 u = 30 ÷ 5 = 6
Amount that each of them has at first
= 1 u + 100
= 6 + 100
= $106
(b)
Amount that Charlie has more than Bryan in the end
= 6 u - 1 u
= 5 u
= 5 x 6
= $30
Answer(s): (a) $106; (b) $30
