3 children have a total of $1760.
Adam has $250 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 + 250
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 250
= 5 u + 250
5 u + 250 = 1760
5 u = 1760 - 250 = 1510
5 u = 1510
1 u = 1510 ÷ 5 = 302
Amount that Adam has
= 2 u + 250
= 2 x 302 + 250
= 604 + 250
= $854
(b)
Amount that Charlie has
= 2 u
= $604
(c)
Amount that Bryan has
= 1 u
= $302
Answer(s): (a) $854; (b) $604; (c) $302
