3 children have a total of $4920.
Bryan has $240 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 + 240
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 240
= 5 u + 240
5 u + 240 = 4920
5 u = 4920 - 240 = 4680
5 u = 4680
1 u = 4680 ÷ 5 = 936
Amount that Bryan has
= 2 u + 240
= 2 x 936 + 240
= 1872 + 240
= $2112
(b)
Amount that Charlie has
= 2 u
= $1872
(c)
Amount that Adam has
= 1 u
= $936
Answer(s): (a) $2112; (b) $1872; (c) $936
