3 children have a total of $3910.
Bryan has $280 more than Adam.
Adam has 5 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 = 5 u
Amount that Bryan has = 5 u + 280
Total amount that Bryan, Adam and Charlie
= 1 u + 5 u + 5 u + 280
= 11 u + 280
11 u + 280 = 3910
11 u = 3910 - 280 = 3630
11 u = 3630
1 u = 3630 ÷ 11 = 330
Amount that Bryan has
= 5 u + 280
= 5 x 330 + 280
= 1650 + 280
= $1930
(b)
Amount that Adam has
= 5 u
= $1650
(c)
Amount that Charlie has
= 1 u
= $330
Answer(s): (a) $1930; (b) $1650; (c) $330
