Before |
6 u - 70 |
1 u - 10 |
Change |
+ 70 |
+ 10 |
After |
6 u |
1 u |
(a)
At first
Amount that Adam has = Amount that Charlie has
6 u - 70 = 1 u - 10
6 u - 1 u = 70 - 10
5 u = 60
1 u = 60 ÷ 5 = 12
Amount that each of them has at first
= 1 u - 10
= 12 - 10
= $2
(b)
Amount that Adam has more than Charlie in the end
= 6 u - 1 u
= 5 u
= 5 x 12
= $60
Answer(s): (a) $2; (b) $60
