3 children have a total of $4370.
Adam has $500 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 + 500
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 500
= 5 u + 500
5 u + 500 = 4370
5 u = 4370 - 500 = 3870
5 u = 3870
1 u = 3870 ÷ 5 = 774
Amount that Adam has
= 2 u + 500
= 2 x 774 + 500
= 1548 + 500
= $2048
(b)
Amount that Charlie has
= 2 u
= $1548
(c)
Amount that Bryan has
= 1 u
= $774
Answer(s): (a) $2048; (b) $1548; (c) $774
