3 children have a total of $4150.
Bryan has $160 more than Adam.
Adam has 2 times as much as Charlie.
- How much does Bryan have?
- How much does Adam have?
- How much does Charlie have?
(a)
Choose the person with least money to be 1 u.
Amount that Charlie has = 1 u
Amount that Adam has = 2 u
Amount that Bryan has = 2 u + 160
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 160
= 5 u + 160
5 u + 160 = 4150
5 u = 4150 - 160 = 3990
5 u = 3990
1 u = 3990 ÷ 5 = 798
Amount that Bryan has
= 2 u + 160
= 2 x 798 + 160
= 1596 + 160
= $1756
(b)
Amount that Adam has
= 2 u
= $1596
(c)
Amount that Charlie has
= 1 u
= $798
Answer(s): (a) $1756; (b) $1596; (c) $798
