3 children have a total of $4860.
Bryan has $300 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 + 300
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 300
= 5 u + 300
5 u + 300 = 4860
5 u = 4860 - 300 = 4560
5 u = 4560
1 u = 4560 ÷ 5 = 912
Amount that Bryan has
= 2 u + 300
= 2 x 912 + 300
= 1824 + 300
= $2124
(b)
Amount that Adam has
= 2 u
= $1824
(c)
Amount that Charlie has
= 1 u
= $912
Answer(s): (a) $2124; (b) $1824; (c) $912
