3 children have a total of $3430.
Bryan has $280 more than Adam.
Adam has 4 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 = 4 u
Amount that Bryan has = 4 u + 280
Total amount that Bryan, Adam and Charlie
= 1 u + 4 u + 4 u + 280
= 9 u + 280
9 u + 280 = 3430
9 u = 3430 - 280 = 3150
9 u = 3150
1 u = 3150 ÷ 9 = 350
Amount that Bryan has
= 4 u + 280
= 4 x 350 + 280
= 1400 + 280
= $1680
(b)
Amount that Adam has
= 4 u
= $1400
(c)
Amount that Charlie has
= 1 u
= $350
Answer(s): (a) $1680; (b) $1400; (c) $350
