3 children have a total of $1960.
Charlie has $210 more than Bryan.
Bryan has 3 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 = 3 u
Amount that Charlie has = 3 u + 210
Total amount that Charlie, Bryan and Adam
= 1 u + 3 u + 3 u + 210
= 7 u + 210
7 u + 210 = 1960
7 u = 1960 - 210 = 1750
7 u = 1750
1 u = 1750 ÷ 7 = 250
Amount that Charlie has
= 3 u + 210
= 3 x 250 + 210
= 750 + 210
= $960
(b)
Amount that Bryan has
= 3 u
= $750
(c)
Amount that Adam has
= 1 u
= $250
Answer(s): (a) $960; (b) $750; (c) $250
