Before |
6 u + 10 |
1 u + 40 |
Change |
- 10 |
- 40 |
After |
6 u |
1 u |
(a)
At first
Amount that Bryan has = Amount that Charlie has
6 u + 10 = 1 u + 40
6 u - 1 u = 40 - 10
5 u = 30
1 u = 30 ÷ 5 = 6
Amount that each of them has at first
= 1 u + 40
= 6 + 40
= $46
(b)
Amount that Charlie has less than Bryan in the end
= 6 u - 1 u
= 5 u
= 5 x 6
= $30
Answer(s): (a) $46; (b) $30
