3 children have a total of $4700.
Bryan has $470 more than Adam.
Adam has 4 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 = 4 u
Amount that Bryan has = 4 u + 470
Total amount that Bryan, Adam and Charlie
= 1 u + 4 u + 4 u + 470
= 9 u + 470
9 u + 470 = 4700
9 u = 4700 - 470 = 4230
9 u = 4230
1 u = 4230 ÷ 9 = 470
Amount that Bryan has
= 4 u + 470
= 4 x 470 + 470
= 1880 + 470
= $2350
(b)
Amount that Adam has
= 4 u
= $1880
(c)
Amount that Charlie has
= 1 u
= $470
Answer(s): (a) $2350; (b) $1880; (c) $470
