3 children have a total of $3770.
Charlie has $130 more than Adam.
Adam has 6 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 = 6 u
Amount that Charlie has = 6 u + 130
Total amount that Charlie, Adam and Bryan
= 1 u + 6 u + 6 u + 130
= 13 u + 130
13 u + 130 = 3770
13 u = 3770 - 130 = 3640
13 u = 3640
1 u = 3640 ÷ 13 = 280
Amount that Charlie has
= 6 u + 130
= 6 x 280 + 130
= 1680 + 130
= $1810
(b)
Amount that Adam has
= 6 u
= $1680
(c)
Amount that Bryan has
= 1 u
= $280
Answer(s): (a) $1810; (b) $1680; (c) $280
