3 children have a total of $4150.
Bryan has $430 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 + 430
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 430
= 5 u + 430
5 u + 430 = 4150
5 u = 4150 - 430 = 3720
5 u = 3720
1 u = 3720 ÷ 5 = 744
Amount that Bryan has
= 2 u + 430
= 2 x 744 + 430
= 1488 + 430
= $1918
(b)
Amount that Charlie has
= 2 u
= $1488
(c)
Amount that Adam has
= 1 u
= $744
Answer(s): (a) $1918; (b) $1488; (c) $744
