3 children have a total of $4750.
Bryan has $330 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 + 330
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 330
= 5 u + 330
5 u + 330 = 4750
5 u = 4750 - 330 = 4420
5 u = 4420
1 u = 4420 ÷ 5 = 884
Amount that Bryan has
= 2 u + 330
= 2 x 884 + 330
= 1768 + 330
= $2098
(b)
Amount that Charlie has
= 2 u
= $1768
(c)
Amount that Adam has
= 1 u
= $884
Answer(s): (a) $2098; (b) $1768; (c) $884
