3 children have a total of $4150.
Bryan has $340 more than Adam.
Adam has 2 times as much as Charlie.
- How much does Bryan have?
- How much does Adam have?
- How much does Charlie have?
(a)
Choose the person with least money to be 1 u.
Amount that Charlie has = 1 u
Amount that Adam has = 2 u
Amount that Bryan has = 2 u + 340
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 340
= 5 u + 340
5 u + 340 = 4150
5 u = 4150 - 340 = 3810
5 u = 3810
1 u = 3810 ÷ 5 = 762
Amount that Bryan has
= 2 u + 340
= 2 x 762 + 340
= 1524 + 340
= $1864
(b)
Amount that Adam has
= 2 u
= $1524
(c)
Amount that Charlie has
= 1 u
= $762
Answer(s): (a) $1864; (b) $1524; (c) $762
