3 children have a total of $2530.
Adam has $450 more than Charlie.
Charlie has 2 times as much as Bryan.
- How much does Adam have?
- How much does Charlie 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 Charlie has = 2 u
Amount that Adam has = 2 u + 450
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 450
= 5 u + 450
5 u + 450 = 2530
5 u = 2530 - 450 = 2080
5 u = 2080
1 u = 2080 ÷ 5 = 416
Amount that Adam has
= 2 u + 450
= 2 x 416 + 450
= 832 + 450
= $1282
(b)
Amount that Charlie has
= 2 u
= $832
(c)
Amount that Bryan has
= 1 u
= $416
Answer(s): (a) $1282; (b) $832; (c) $416
