3 children have a total of $2940.
Charlie has $260 more than Adam.
Adam has 2 times as much as Bryan.
- How much does Charlie have?
- How much does Adam have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Adam has = 2 u
Amount that Charlie has = 2 u + 260
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 260
= 5 u + 260
5 u + 260 = 2940
5 u = 2940 - 260 = 2680
5 u = 2680
1 u = 2680 ÷ 5 = 536
Amount that Charlie has
= 2 u + 260
= 2 x 536 + 260
= 1072 + 260
= $1332
(b)
Amount that Adam has
= 2 u
= $1072
(c)
Amount that Bryan has
= 1 u
= $536
Answer(s): (a) $1332; (b) $1072; (c) $536
