3 children have a total of $4060.
Charlie has $320 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 + 320
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 320
= 5 u + 320
5 u + 320 = 4060
5 u = 4060 - 320 = 3740
5 u = 3740
1 u = 3740 ÷ 5 = 748
Amount that Charlie has
= 2 u + 320
= 2 x 748 + 320
= 1496 + 320
= $1816
(b)
Amount that Bryan has
= 2 u
= $1496
(c)
Amount that Adam has
= 1 u
= $748
Answer(s): (a) $1816; (b) $1496; (c) $748
