3 children have a total of $4040.
Charlie has $270 more than Bryan.
Bryan has 2 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 = 2 u
Amount that Charlie has = 2 u + 270
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 270
= 5 u + 270
5 u + 270 = 4040
5 u = 4040 - 270 = 3770
5 u = 3770
1 u = 3770 ÷ 5 = 754
Amount that Charlie has
= 2 u + 270
= 2 x 754 + 270
= 1508 + 270
= $1778
(b)
Amount that Bryan has
= 2 u
= $1508
(c)
Amount that Adam has
= 1 u
= $754
Answer(s): (a) $1778; (b) $1508; (c) $754
