3 children have a total of $4710.
Bryan has $310 more than Charlie.
Charlie has 5 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 = 5 u
Amount that Bryan has = 5 u + 310
Total amount that Bryan, Charlie and Adam
= 1 u + 5 u + 5 u + 310
= 11 u + 310
11 u + 310 = 4710
11 u = 4710 - 310 = 4400
11 u = 4400
1 u = 4400 ÷ 11 = 400
Amount that Bryan has
= 5 u + 310
= 5 x 400 + 310
= 2000 + 310
= $2310
(b)
Amount that Charlie has
= 5 u
= $2000
(c)
Amount that Adam has
= 1 u
= $400
Answer(s): (a) $2310; (b) $2000; (c) $400
