3 children have a total of $1060.
Charlie has $160 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 + 160
Total amount that Charlie, Bryan and Adam
= 1 u + 4 u + 4 u + 160
= 9 u + 160
9 u + 160 = 1060
9 u = 1060 - 160 = 900
9 u = 900
1 u = 900 ÷ 9 = 100
Amount that Charlie has
= 4 u + 160
= 4 x 100 + 160
= 400 + 160
= $560
(b)
Amount that Bryan has
= 4 u
= $400
(c)
Amount that Adam has
= 1 u
= $100
Answer(s): (a) $560; (b) $400; (c) $100
