3 children have a total of $3570.
Bryan has $450 more than Charlie.
Charlie has 2 times as much as Adam.
- How much does Bryan have?
- How much does Charlie 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 Charlie has = 2 u
Amount that Bryan has = 2 u + 450
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 450
= 5 u + 450
5 u + 450 = 3570
5 u = 3570 - 450 = 3120
5 u = 3120
1 u = 3120 ÷ 5 = 624
Amount that Bryan has
= 2 u + 450
= 2 x 624 + 450
= 1248 + 450
= $1698
(b)
Amount that Charlie has
= 2 u
= $1248
(c)
Amount that Adam has
= 1 u
= $624
Answer(s): (a) $1698; (b) $1248; (c) $624
