3 children have a total of $3390.
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 = 3390
5 u = 3390 - 430 = 2960
5 u = 2960
1 u = 2960 ÷ 5 = 592
Amount that Bryan has
= 2 u + 430
= 2 x 592 + 430
= 1184 + 430
= $1614
(b)
Amount that Charlie has
= 2 u
= $1184
(c)
Amount that Adam has
= 1 u
= $592
Answer(s): (a) $1614; (b) $1184; (c) $592
