3 children have a total of $4910.
Charlie has $400 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 + 400
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 400
= 5 u + 400
5 u + 400 = 4910
5 u = 4910 - 400 = 4510
5 u = 4510
1 u = 4510 ÷ 5 = 902
Amount that Charlie has
= 2 u + 400
= 2 x 902 + 400
= 1804 + 400
= $2204
(b)
Amount that Bryan has
= 2 u
= $1804
(c)
Amount that Adam has
= 1 u
= $902
Answer(s): (a) $2204; (b) $1804; (c) $902
