3 children have a total of $1880.
Adam has $470 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 + 470
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 470
= 5 u + 470
5 u + 470 = 1880
5 u = 1880 - 470 = 1410
5 u = 1410
1 u = 1410 ÷ 5 = 282
Amount that Adam has
= 2 u + 470
= 2 x 282 + 470
= 564 + 470
= $1034
(b)
Amount that Charlie has
= 2 u
= $564
(c)
Amount that Bryan has
= 1 u
= $282
Answer(s): (a) $1034; (b) $564; (c) $282
