3 children have a total of $4450.
Charlie has $490 more than Bryan.
Bryan has 4 times as much as Adam.
- How much does Charlie have?
- How much does Bryan 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 Bryan has = 4 u
Amount that Charlie has = 4 u + 490
Total amount that Charlie, Bryan and Adam
= 1 u + 4 u + 4 u + 490
= 9 u + 490
9 u + 490 = 4450
9 u = 4450 - 490 = 3960
9 u = 3960
1 u = 3960 ÷ 9 = 440
Amount that Charlie has
= 4 u + 490
= 4 x 440 + 490
= 1760 + 490
= $2250
(b)
Amount that Bryan has
= 4 u
= $1760
(c)
Amount that Adam has
= 1 u
= $440
Answer(s): (a) $2250; (b) $1760; (c) $440
