3 children have a total of $3510.
Bryan has $360 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 + 360
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 360
= 5 u + 360
5 u + 360 = 3510
5 u = 3510 - 360 = 3150
5 u = 3150
1 u = 3150 ÷ 5 = 630
Amount that Bryan has
= 2 u + 360
= 2 x 630 + 360
= 1260 + 360
= $1620
(b)
Amount that Charlie has
= 2 u
= $1260
(c)
Amount that Adam has
= 1 u
= $630
Answer(s): (a) $1620; (b) $1260; (c) $630
