3 children have a total of $1480.
Bryan has $370 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 + 370
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 370
= 5 u + 370
5 u + 370 = 1480
5 u = 1480 - 370 = 1110
5 u = 1110
1 u = 1110 ÷ 5 = 222
Amount that Bryan has
= 2 u + 370
= 2 x 222 + 370
= 444 + 370
= $814
(b)
Amount that Charlie has
= 2 u
= $444
(c)
Amount that Adam has
= 1 u
= $222
Answer(s): (a) $814; (b) $444; (c) $222
