3 children have a total of $3040.
Charlie has $470 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 + 470
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 470
= 5 u + 470
5 u + 470 = 3040
5 u = 3040 - 470 = 2570
5 u = 2570
1 u = 2570 ÷ 5 = 514
Amount that Charlie has
= 2 u + 470
= 2 x 514 + 470
= 1028 + 470
= $1498
(b)
Amount that Adam has
= 2 u
= $1028
(c)
Amount that Bryan has
= 1 u
= $514
Answer(s): (a) $1498; (b) $1028; (c) $514
