3 children have a total of $3270.
Bryan has $340 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 + 340
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 340
= 5 u + 340
5 u + 340 = 3270
5 u = 3270 - 340 = 2930
5 u = 2930
1 u = 2930 ÷ 5 = 586
Amount that Bryan has
= 2 u + 340
= 2 x 586 + 340
= 1172 + 340
= $1512
(b)
Amount that Charlie has
= 2 u
= $1172
(c)
Amount that Adam has
= 1 u
= $586
Answer(s): (a) $1512; (b) $1172; (c) $586
