3 children have a total of $1940.
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 = 1940
5 u = 1940 - 230 = 1710
5 u = 1710
1 u = 1710 ÷ 5 = 342
Amount that Bryan has
= 2 u + 230
= 2 x 342 + 230
= 684 + 230
= $914
(b)
Amount that Adam has
= 2 u
= $684
(c)
Amount that Charlie has
= 1 u
= $342
Answer(s): (a) $914; (b) $684; (c) $342
