3 children have a total of $2180.
Charlie has $110 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 + 110
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 110
= 5 u + 110
5 u + 110 = 2180
5 u = 2180 - 110 = 2070
5 u = 2070
1 u = 2070 ÷ 5 = 414
Amount that Charlie has
= 2 u + 110
= 2 x 414 + 110
= 828 + 110
= $938
(b)
Amount that Bryan has
= 2 u
= $828
(c)
Amount that Adam has
= 1 u
= $414
Answer(s): (a) $938; (b) $828; (c) $414
