3 children have a total of $4530.
Adam has $300 more than Charlie.
Charlie has 2 times as much as Bryan.
- How much does Adam have?
- How much does Charlie 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 Charlie has = 2 u
Amount that Adam has = 2 u + 300
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 300
= 5 u + 300
5 u + 300 = 4530
5 u = 4530 - 300 = 4230
5 u = 4230
1 u = 4230 ÷ 5 = 846
Amount that Adam has
= 2 u + 300
= 2 x 846 + 300
= 1692 + 300
= $1992
(b)
Amount that Charlie has
= 2 u
= $1692
(c)
Amount that Bryan has
= 1 u
= $846
Answer(s): (a) $1992; (b) $1692; (c) $846
