3 children have a total of $2460.
Charlie has $280 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 + 280
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 280
= 5 u + 280
5 u + 280 = 2460
5 u = 2460 - 280 = 2180
5 u = 2180
1 u = 2180 ÷ 5 = 436
Amount that Charlie has
= 2 u + 280
= 2 x 436 + 280
= 872 + 280
= $1152
(b)
Amount that Adam has
= 2 u
= $872
(c)
Amount that Bryan has
= 1 u
= $436
Answer(s): (a) $1152; (b) $872; (c) $436
