3 children have a total of $2190.
Bryan has $250 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 + 250
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 250
= 5 u + 250
5 u + 250 = 2190
5 u = 2190 - 250 = 1940
5 u = 1940
1 u = 1940 ÷ 5 = 388
Amount that Bryan has
= 2 u + 250
= 2 x 388 + 250
= 776 + 250
= $1026
(b)
Amount that Adam has
= 2 u
= $776
(c)
Amount that Charlie has
= 1 u
= $388
Answer(s): (a) $1026; (b) $776; (c) $388
