3 children have a total of $3360.
Bryan has $300 more than Charlie.
Charlie has 4 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 = 4 u
Amount that Bryan has = 4 u + 300
Total amount that Bryan, Charlie and Adam
= 1 u + 4 u + 4 u + 300
= 9 u + 300
9 u + 300 = 3360
9 u = 3360 - 300 = 3060
9 u = 3060
1 u = 3060 ÷ 9 = 340
Amount that Bryan has
= 4 u + 300
= 4 x 340 + 300
= 1360 + 300
= $1660
(b)
Amount that Charlie has
= 4 u
= $1360
(c)
Amount that Adam has
= 1 u
= $340
Answer(s): (a) $1660; (b) $1360; (c) $340
