3 children have a total of $4300.
Charlie has $220 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 + 220
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 220
= 5 u + 220
5 u + 220 = 4300
5 u = 4300 - 220 = 4080
5 u = 4080
1 u = 4080 ÷ 5 = 816
Amount that Charlie has
= 2 u + 220
= 2 x 816 + 220
= 1632 + 220
= $1852
(b)
Amount that Bryan has
= 2 u
= $1632
(c)
Amount that Adam has
= 1 u
= $816
Answer(s): (a) $1852; (b) $1632; (c) $816
