3 children have a total of $1820.
Bryan has $250 more than Charlie.
Charlie has 2 times as much as Adam.
- How much does Bryan have?
- How much does Charlie have?
- How much does Adam have?
(a)
Choose the person with least money to be 1 u.
Amount that Adam has = 1 u
Amount that Charlie has = 2 u
Amount that Bryan has = 2 u + 250
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 250
= 5 u + 250
5 u + 250 = 1820
5 u = 1820 - 250 = 1570
5 u = 1570
1 u = 1570 ÷ 5 = 314
Amount that Bryan has
= 2 u + 250
= 2 x 314 + 250
= 628 + 250
= $878
(b)
Amount that Charlie has
= 2 u
= $628
(c)
Amount that Adam has
= 1 u
= $314
Answer(s): (a) $878; (b) $628; (c) $314
