3 children have a total of $4740.
Bryan has $110 more than Charlie.
Charlie has 2 times as much as Adam.
- How much does Bryan have?
- How much does Charlie 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 Charlie has = 2 u
Amount that Bryan has = 2 u + 110
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 110
= 5 u + 110
5 u + 110 = 4740
5 u = 4740 - 110 = 4630
5 u = 4630
1 u = 4630 ÷ 5 = 926
Amount that Bryan has
= 2 u + 110
= 2 x 926 + 110
= 1852 + 110
= $1962
(b)
Amount that Charlie has
= 2 u
= $1852
(c)
Amount that Adam has
= 1 u
= $926
Answer(s): (a) $1962; (b) $1852; (c) $926
