3 children have a total of $2210.
Charlie has $250 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 + 250
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 250
= 5 u + 250
5 u + 250 = 2210
5 u = 2210 - 250 = 1960
5 u = 1960
1 u = 1960 ÷ 5 = 392
Amount that Charlie has
= 2 u + 250
= 2 x 392 + 250
= 784 + 250
= $1034
(b)
Amount that Bryan has
= 2 u
= $784
(c)
Amount that Adam has
= 1 u
= $392
Answer(s): (a) $1034; (b) $784; (c) $392
