3 children have a total of $1570.
Bryan has $230 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 + 230
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 230
= 5 u + 230
5 u + 230 = 1570
5 u = 1570 - 230 = 1340
5 u = 1340
1 u = 1340 ÷ 5 = 268
Amount that Bryan has
= 2 u + 230
= 2 x 268 + 230
= 536 + 230
= $766
(b)
Amount that Charlie has
= 2 u
= $536
(c)
Amount that Adam has
= 1 u
= $268
Answer(s): (a) $766; (b) $536; (c) $268
