3 children have a total of $3150.
Charlie has $290 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 + 290
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 290
= 5 u + 290
5 u + 290 = 3150
5 u = 3150 - 290 = 2860
5 u = 2860
1 u = 2860 ÷ 5 = 572
Amount that Charlie has
= 2 u + 290
= 2 x 572 + 290
= 1144 + 290
= $1434
(b)
Amount that Bryan has
= 2 u
= $1144
(c)
Amount that Adam has
= 1 u
= $572
Answer(s): (a) $1434; (b) $1144; (c) $572
