3 children have a total of $3760.
Adam has $240 more than Bryan.
Bryan has 2 times as much as Charlie.
- How much does Adam have?
- How much does Bryan 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 Bryan has = 2 u
Amount that Adam has = 2 u + 240
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 240
= 5 u + 240
5 u + 240 = 3760
5 u = 3760 - 240 = 3520
5 u = 3520
1 u = 3520 ÷ 5 = 704
Amount that Adam has
= 2 u + 240
= 2 x 704 + 240
= 1408 + 240
= $1648
(b)
Amount that Bryan has
= 2 u
= $1408
(c)
Amount that Charlie has
= 1 u
= $704
Answer(s): (a) $1648; (b) $1408; (c) $704
