3 children have a total of $3730.
Charlie has $150 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 + 150
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 150
= 5 u + 150
5 u + 150 = 3730
5 u = 3730 - 150 = 3580
5 u = 3580
1 u = 3580 ÷ 5 = 716
Amount that Charlie has
= 2 u + 150
= 2 x 716 + 150
= 1432 + 150
= $1582
(b)
Amount that Bryan has
= 2 u
= $1432
(c)
Amount that Adam has
= 1 u
= $716
Answer(s): (a) $1582; (b) $1432; (c) $716
