3 children have a total of $2460.
Charlie has $390 more than Bryan.
Bryan has 4 times as much as Adam.
- How much does Charlie have?
- How much does Bryan 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 Bryan has = 4 u
Amount that Charlie has = 4 u + 390
Total amount that Charlie, Bryan and Adam
= 1 u + 4 u + 4 u + 390
= 9 u + 390
9 u + 390 = 2460
9 u = 2460 - 390 = 2070
9 u = 2070
1 u = 2070 ÷ 9 = 230
Amount that Charlie has
= 4 u + 390
= 4 x 230 + 390
= 920 + 390
= $1310
(b)
Amount that Bryan has
= 4 u
= $920
(c)
Amount that Adam has
= 1 u
= $230
Answer(s): (a) $1310; (b) $920; (c) $230
