3 children have a total of $4060.
Bryan has $440 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 + 440
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 440
= 5 u + 440
5 u + 440 = 4060
5 u = 4060 - 440 = 3620
5 u = 3620
1 u = 3620 ÷ 5 = 724
Amount that Bryan has
= 2 u + 440
= 2 x 724 + 440
= 1448 + 440
= $1888
(b)
Amount that Adam has
= 2 u
= $1448
(c)
Amount that Charlie has
= 1 u
= $724
Answer(s): (a) $1888; (b) $1448; (c) $724
