3 children have a total of $4800.
Charlie has $200 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 + 200
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 200
= 5 u + 200
5 u + 200 = 4800
5 u = 4800 - 200 = 4600
5 u = 4600
1 u = 4600 ÷ 5 = 920
Amount that Charlie has
= 2 u + 200
= 2 x 920 + 200
= 1840 + 200
= $2040
(b)
Amount that Bryan has
= 2 u
= $1840
(c)
Amount that Adam has
= 1 u
= $920
Answer(s): (a) $2040; (b) $1840; (c) $920
