3 children have a total of $4060.
Adam has $110 more than Bryan.
Bryan has 2 times as much as Charlie.
- How much does Adam have?
- How much does Bryan 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 Bryan has = 2 u
Amount that Adam has = 2 u + 110
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 110
= 5 u + 110
5 u + 110 = 4060
5 u = 4060 - 110 = 3950
5 u = 3950
1 u = 3950 ÷ 5 = 790
Amount that Adam has
= 2 u + 110
= 2 x 790 + 110
= 1580 + 110
= $1690
(b)
Amount that Bryan has
= 2 u
= $1580
(c)
Amount that Charlie has
= 1 u
= $790
Answer(s): (a) $1690; (b) $1580; (c) $790
