3 children have a total of $3490.
Bryan has $160 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 + 160
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 160
= 5 u + 160
5 u + 160 = 3490
5 u = 3490 - 160 = 3330
5 u = 3330
1 u = 3330 ÷ 5 = 666
Amount that Bryan has
= 2 u + 160
= 2 x 666 + 160
= 1332 + 160
= $1492
(b)
Amount that Charlie has
= 2 u
= $1332
(c)
Amount that Adam has
= 1 u
= $666
Answer(s): (a) $1492; (b) $1332; (c) $666
