3 children have a total of $4110.
Bryan has $430 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 + 430
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 430
= 5 u + 430
5 u + 430 = 4110
5 u = 4110 - 430 = 3680
5 u = 3680
1 u = 3680 ÷ 5 = 736
Amount that Bryan has
= 2 u + 430
= 2 x 736 + 430
= 1472 + 430
= $1902
(b)
Amount that Adam has
= 2 u
= $1472
(c)
Amount that Charlie has
= 1 u
= $736
Answer(s): (a) $1902; (b) $1472; (c) $736
