3 children have a total of $4580.
Bryan has $370 more than Charlie.
Charlie has 2 times as much as Adam.
- How much does Bryan have?
- How much does Charlie 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 Charlie has = 2 u
Amount that Bryan has = 2 u + 370
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 370
= 5 u + 370
5 u + 370 = 4580
5 u = 4580 - 370 = 4210
5 u = 4210
1 u = 4210 ÷ 5 = 842
Amount that Bryan has
= 2 u + 370
= 2 x 842 + 370
= 1684 + 370
= $2054
(b)
Amount that Charlie has
= 2 u
= $1684
(c)
Amount that Adam has
= 1 u
= $842
Answer(s): (a) $2054; (b) $1684; (c) $842
