3 children have a total of $3020.
Adam has $280 more than Bryan.
Bryan has 2 times as much as Charlie.
- How much does Adam have?
- How much does Bryan have?
- How much does Charlie have?
(a)
Choose the person with least money to be 1 u.
Amount that Charlie has = 1 u
Amount that Bryan has = 2 u
Amount that Adam has = 2 u + 280
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 280
= 5 u + 280
5 u + 280 = 3020
5 u = 3020 - 280 = 2740
5 u = 2740
1 u = 2740 ÷ 5 = 548
Amount that Adam has
= 2 u + 280
= 2 x 548 + 280
= 1096 + 280
= $1376
(b)
Amount that Bryan has
= 2 u
= $1096
(c)
Amount that Charlie has
= 1 u
= $548
Answer(s): (a) $1376; (b) $1096; (c) $548
