3 children have a total of $1730.
Charlie has $200 more than Adam.
Adam has 2 times as much as Bryan.
- How much does Charlie have?
- How much does Adam have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Adam has = 2 u
Amount that Charlie has = 2 u + 200
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 200
= 5 u + 200
5 u + 200 = 1730
5 u = 1730 - 200 = 1530
5 u = 1530
1 u = 1530 ÷ 5 = 306
Amount that Charlie has
= 2 u + 200
= 2 x 306 + 200
= 612 + 200
= $812
(b)
Amount that Adam has
= 2 u
= $612
(c)
Amount that Bryan has
= 1 u
= $306
Answer(s): (a) $812; (b) $612; (c) $306
