3 children have a total of $2640.
Charlie has $110 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 + 110
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 110
= 5 u + 110
5 u + 110 = 2640
5 u = 2640 - 110 = 2530
5 u = 2530
1 u = 2530 ÷ 5 = 506
Amount that Charlie has
= 2 u + 110
= 2 x 506 + 110
= 1012 + 110
= $1122
(b)
Amount that Adam has
= 2 u
= $1012
(c)
Amount that Bryan has
= 1 u
= $506
Answer(s): (a) $1122; (b) $1012; (c) $506
