3 children have a total of $2080.
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 = 2080
5 u = 2080 - 240 = 1840
5 u = 1840
1 u = 1840 ÷ 5 = 368
Amount that Bryan has
= 2 u + 240
= 2 x 368 + 240
= 736 + 240
= $976
(b)
Amount that Charlie has
= 2 u
= $736
(c)
Amount that Adam has
= 1 u
= $368
Answer(s): (a) $976; (b) $736; (c) $368
