3 children have a total of $4820.
Charlie has $500 more than Bryan.
Bryan has 2 times as much as Adam.
- How much does Charlie have?
- How much does Bryan have?
- How much does Adam have?
(a)
Choose the person with least money to be 1 u.
Amount that Adam has = 1 u
Amount that Bryan has = 2 u
Amount that Charlie has = 2 u + 500
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 500
= 5 u + 500
5 u + 500 = 4820
5 u = 4820 - 500 = 4320
5 u = 4320
1 u = 4320 ÷ 5 = 864
Amount that Charlie has
= 2 u + 500
= 2 x 864 + 500
= 1728 + 500
= $2228
(b)
Amount that Bryan has
= 2 u
= $1728
(c)
Amount that Adam has
= 1 u
= $864
Answer(s): (a) $2228; (b) $1728; (c) $864
