3 children have a total of $4290.
Charlie has $330 more than Bryan.
Bryan has 5 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 = 5 u
Amount that Charlie has = 5 u + 330
Total amount that Charlie, Bryan and Adam
= 1 u + 5 u + 5 u + 330
= 11 u + 330
11 u + 330 = 4290
11 u = 4290 - 330 = 3960
11 u = 3960
1 u = 3960 ÷ 11 = 360
Amount that Charlie has
= 5 u + 330
= 5 x 360 + 330
= 1800 + 330
= $2130
(b)
Amount that Bryan has
= 5 u
= $1800
(c)
Amount that Adam has
= 1 u
= $360
Answer(s): (a) $2130; (b) $1800; (c) $360
