3 children have a total of $3200.
Bryan has $500 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 + 500
Total amount that Bryan, Adam and Charlie
= 1 u + 4 u + 4 u + 500
= 9 u + 500
9 u + 500 = 3200
9 u = 3200 - 500 = 2700
9 u = 2700
1 u = 2700 ÷ 9 = 300
Amount that Bryan has
= 4 u + 500
= 4 x 300 + 500
= 1200 + 500
= $1700
(b)
Amount that Adam has
= 4 u
= $1200
(c)
Amount that Charlie has
= 1 u
= $300
Answer(s): (a) $1700; (b) $1200; (c) $300
