3 children have a total of $2020.
Charlie has $480 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 + 480
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 480
= 5 u + 480
5 u + 480 = 2020
5 u = 2020 - 480 = 1540
5 u = 1540
1 u = 1540 ÷ 5 = 308
Amount that Charlie has
= 2 u + 480
= 2 x 308 + 480
= 616 + 480
= $1096
(b)
Amount that Bryan has
= 2 u
= $616
(c)
Amount that Adam has
= 1 u
= $308
Answer(s): (a) $1096; (b) $616; (c) $308
