3 children have a total of $2660.
Bryan has $180 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 + 180
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 180
= 5 u + 180
5 u + 180 = 2660
5 u = 2660 - 180 = 2480
5 u = 2480
1 u = 2480 ÷ 5 = 496
Amount that Bryan has
= 2 u + 180
= 2 x 496 + 180
= 992 + 180
= $1172
(b)
Amount that Adam has
= 2 u
= $992
(c)
Amount that Charlie has
= 1 u
= $496
Answer(s): (a) $1172; (b) $992; (c) $496
