3 children have a total of $3670.
Charlie has $330 more than Adam.
Adam has 2 times as much as Bryan.
- How much does Charlie have?
- How much does Adam have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Adam has = 2 u
Amount that Charlie has = 2 u + 330
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 330
= 5 u + 330
5 u + 330 = 3670
5 u = 3670 - 330 = 3340
5 u = 3340
1 u = 3340 ÷ 5 = 668
Amount that Charlie has
= 2 u + 330
= 2 x 668 + 330
= 1336 + 330
= $1666
(b)
Amount that Adam has
= 2 u
= $1336
(c)
Amount that Bryan has
= 1 u
= $668
Answer(s): (a) $1666; (b) $1336; (c) $668
