3 children have a total of $1940.
Charlie has $260 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 + 260
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 260
= 5 u + 260
5 u + 260 = 1940
5 u = 1940 - 260 = 1680
5 u = 1680
1 u = 1680 ÷ 5 = 336
Amount that Charlie has
= 2 u + 260
= 2 x 336 + 260
= 672 + 260
= $932
(b)
Amount that Bryan has
= 2 u
= $672
(c)
Amount that Adam has
= 1 u
= $336
Answer(s): (a) $932; (b) $672; (c) $336
