3 children have a total of $3470.
Charlie has $160 more than Bryan.
Bryan has 2 times as much as Adam.
- How much does Charlie have?
- How much does Bryan 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 Bryan has = 2 u
Amount that Charlie has = 2 u + 160
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 160
= 5 u + 160
5 u + 160 = 3470
5 u = 3470 - 160 = 3310
5 u = 3310
1 u = 3310 ÷ 5 = 662
Amount that Charlie has
= 2 u + 160
= 2 x 662 + 160
= 1324 + 160
= $1484
(b)
Amount that Bryan has
= 2 u
= $1324
(c)
Amount that Adam has
= 1 u
= $662
Answer(s): (a) $1484; (b) $1324; (c) $662
