Total |
Before |
8 u |
5 u |
13 u |
Change |
- 4.8 u |
+ 4.8 u |
|
After |
3.2 u |
9.8 u |
13 u |
The total amount that the 2 boys have remains the same.
Amount that Bryan gives to Adam
=
35 x 8 u
= 4.8 u
Amount that Bryan has less than Adam in the end
= 9.8 u - 3.2 u
= 6.6 u
6.6 u = 330
1 u = 330 ÷ 6.6 = 50
(a)
Amount that Adam has at first
= 5 u
= 5 x 50
= $250
(b)
Amount that Bryan has in the end
= 3.2 u
= 3.2 x 50
= $160
(c)
Amount that Bryan gives to Adam
= 4.8 u
= 4.8 x 50
= $240
Answer(s): (a) $250; (b) $160; (c) $240
