3 children have a total of $4570.
Bryan has $340 more than Charlie.
Charlie has 4 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 = 4 u
Amount that Bryan has = 4 u + 340
Total amount that Bryan, Charlie and Adam
= 1 u + 4 u + 4 u + 340
= 9 u + 340
9 u + 340 = 4570
9 u = 4570 - 340 = 4230
9 u = 4230
1 u = 4230 ÷ 9 = 470
Amount that Bryan has
= 4 u + 340
= 4 x 470 + 340
= 1880 + 340
= $2220
(b)
Amount that Charlie has
= 4 u
= $1880
(c)
Amount that Adam has
= 1 u
= $470
Answer(s): (a) $2220; (b) $1880; (c) $470
