3 children have a total of $3810.
Bryan has $290 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 + 290
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 290
= 5 u + 290
5 u + 290 = 3810
5 u = 3810 - 290 = 3520
5 u = 3520
1 u = 3520 ÷ 5 = 704
Amount that Bryan has
= 2 u + 290
= 2 x 704 + 290
= 1408 + 290
= $1698
(b)
Amount that Charlie has
= 2 u
= $1408
(c)
Amount that Adam has
= 1 u
= $704
Answer(s): (a) $1698; (b) $1408; (c) $704
