3 children have a total of $2540.
Bryan has $200 more than Adam.
Adam has 2 times as much as Charlie.
- How much does Bryan have?
- How much does Adam have?
- How much does Charlie have?
(a)
Choose the person with least money to be 1 u.
Amount that Charlie has = 1 u
Amount that Adam has = 2 u
Amount that Bryan has = 2 u + 200
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 200
= 5 u + 200
5 u + 200 = 2540
5 u = 2540 - 200 = 2340
5 u = 2340
1 u = 2340 ÷ 5 = 468
Amount that Bryan has
= 2 u + 200
= 2 x 468 + 200
= 936 + 200
= $1136
(b)
Amount that Adam has
= 2 u
= $936
(c)
Amount that Charlie has
= 1 u
= $468
Answer(s): (a) $1136; (b) $936; (c) $468
