3 children have a total of $4620.
Charlie has $460 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 + 460
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 460
= 5 u + 460
5 u + 460 = 4620
5 u = 4620 - 460 = 4160
5 u = 4160
1 u = 4160 ÷ 5 = 832
Amount that Charlie has
= 2 u + 460
= 2 x 832 + 460
= 1664 + 460
= $2124
(b)
Amount that Adam has
= 2 u
= $1664
(c)
Amount that Bryan has
= 1 u
= $832
Answer(s): (a) $2124; (b) $1664; (c) $832
