3 children have a total of $4050.
Bryan has $220 more than Adam.
Adam has 2 times as much as Charlie.
- How much does Bryan have?
- How much does Adam have?
- How much does Charlie have?
(a)
Choose the person with least money to be 1 u.
Amount that Charlie has = 1 u
Amount that Adam has = 2 u
Amount that Bryan has = 2 u + 220
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 220
= 5 u + 220
5 u + 220 = 4050
5 u = 4050 - 220 = 3830
5 u = 3830
1 u = 3830 ÷ 5 = 766
Amount that Bryan has
= 2 u + 220
= 2 x 766 + 220
= 1532 + 220
= $1752
(b)
Amount that Adam has
= 2 u
= $1532
(c)
Amount that Charlie has
= 1 u
= $766
Answer(s): (a) $1752; (b) $1532; (c) $766
