3 children have a total of $4810.
Adam has $460 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 + 460
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 460
= 5 u + 460
5 u + 460 = 4810
5 u = 4810 - 460 = 4350
5 u = 4350
1 u = 4350 ÷ 5 = 870
Amount that Adam has
= 2 u + 460
= 2 x 870 + 460
= 1740 + 460
= $2200
(b)
Amount that Charlie has
= 2 u
= $1740
(c)
Amount that Bryan has
= 1 u
= $870
Answer(s): (a) $2200; (b) $1740; (c) $870
