3 children have a total of $2280.
Charlie has $200 more than Bryan.
Bryan has 6 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 = 6 u
Amount that Charlie has = 6 u + 200
Total amount that Charlie, Bryan and Adam
= 1 u + 6 u + 6 u + 200
= 13 u + 200
13 u + 200 = 2280
13 u = 2280 - 200 = 2080
13 u = 2080
1 u = 2080 ÷ 13 = 160
Amount that Charlie has
= 6 u + 200
= 6 x 160 + 200
= 960 + 200
= $1160
(b)
Amount that Bryan has
= 6 u
= $960
(c)
Amount that Adam has
= 1 u
= $160
Answer(s): (a) $1160; (b) $960; (c) $160
