3 children have a total of $1350.
Charlie has $300 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 + 300
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 300
= 5 u + 300
5 u + 300 = 1350
5 u = 1350 - 300 = 1050
5 u = 1050
1 u = 1050 ÷ 5 = 210
Amount that Charlie has
= 2 u + 300
= 2 x 210 + 300
= 420 + 300
= $720
(b)
Amount that Adam has
= 2 u
= $420
(c)
Amount that Bryan has
= 1 u
= $210
Answer(s): (a) $720; (b) $420; (c) $210
