3 children have a total of $4330.
Charlie has $350 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 + 350
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 350
= 5 u + 350
5 u + 350 = 4330
5 u = 4330 - 350 = 3980
5 u = 3980
1 u = 3980 ÷ 5 = 796
Amount that Charlie has
= 2 u + 350
= 2 x 796 + 350
= 1592 + 350
= $1942
(b)
Amount that Bryan has
= 2 u
= $1592
(c)
Amount that Adam has
= 1 u
= $796
Answer(s): (a) $1942; (b) $1592; (c) $796
