3 children have a total of $1590.
Bryan has $230 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 + 230
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 230
= 5 u + 230
5 u + 230 = 1590
5 u = 1590 - 230 = 1360
5 u = 1360
1 u = 1360 ÷ 5 = 272
Amount that Bryan has
= 2 u + 230
= 2 x 272 + 230
= 544 + 230
= $774
(b)
Amount that Adam has
= 2 u
= $544
(c)
Amount that Charlie has
= 1 u
= $272
Answer(s): (a) $774; (b) $544; (c) $272
