3 children have a total of $3880.
Bryan has $310 more than Adam.
Adam has 3 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 = 3 u
Amount that Bryan has = 3 u + 310
Total amount that Bryan, Adam and Charlie
= 1 u + 3 u + 3 u + 310
= 7 u + 310
7 u + 310 = 3880
7 u = 3880 - 310 = 3570
7 u = 3570
1 u = 3570 ÷ 7 = 510
Amount that Bryan has
= 3 u + 310
= 3 x 510 + 310
= 1530 + 310
= $1840
(b)
Amount that Adam has
= 3 u
= $1530
(c)
Amount that Charlie has
= 1 u
= $510
Answer(s): (a) $1840; (b) $1530; (c) $510
