3 children have a total of $1040.
Bryan has $370 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 + 370
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 370
= 5 u + 370
5 u + 370 = 1040
5 u = 1040 - 370 = 670
5 u = 670
1 u = 670 ÷ 5 = 134
Amount that Bryan has
= 2 u + 370
= 2 x 134 + 370
= 268 + 370
= $638
(b)
Amount that Adam has
= 2 u
= $268
(c)
Amount that Charlie has
= 1 u
= $134
Answer(s): (a) $638; (b) $268; (c) $134
