3 children have a total of $1990.
Bryan has $480 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 + 480
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 480
= 5 u + 480
5 u + 480 = 1990
5 u = 1990 - 480 = 1510
5 u = 1510
1 u = 1510 ÷ 5 = 302
Amount that Bryan has
= 2 u + 480
= 2 x 302 + 480
= 604 + 480
= $1084
(b)
Amount that Charlie has
= 2 u
= $604
(c)
Amount that Adam has
= 1 u
= $302
Answer(s): (a) $1084; (b) $604; (c) $302
