3 children have a total of $3310.
Bryan has $400 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 + 400
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 400
= 5 u + 400
5 u + 400 = 3310
5 u = 3310 - 400 = 2910
5 u = 2910
1 u = 2910 ÷ 5 = 582
Amount that Bryan has
= 2 u + 400
= 2 x 582 + 400
= 1164 + 400
= $1564
(b)
Amount that Adam has
= 2 u
= $1164
(c)
Amount that Charlie has
= 1 u
= $582
Answer(s): (a) $1564; (b) $1164; (c) $582
