3 children have a total of $4540.
Bryan has $270 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 + 270
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 270
= 5 u + 270
5 u + 270 = 4540
5 u = 4540 - 270 = 4270
5 u = 4270
1 u = 4270 ÷ 5 = 854
Amount that Bryan has
= 2 u + 270
= 2 x 854 + 270
= 1708 + 270
= $1978
(b)
Amount that Charlie has
= 2 u
= $1708
(c)
Amount that Adam has
= 1 u
= $854
Answer(s): (a) $1978; (b) $1708; (c) $854
