3 children have a total of $4840.
Adam has $220 more than Bryan.
Bryan has 2 times as much as Charlie.
- How much does Adam have?
- How much does Bryan 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 Bryan has = 2 u
Amount that Adam has = 2 u + 220
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 220
= 5 u + 220
5 u + 220 = 4840
5 u = 4840 - 220 = 4620
5 u = 4620
1 u = 4620 ÷ 5 = 924
Amount that Adam has
= 2 u + 220
= 2 x 924 + 220
= 1848 + 220
= $2068
(b)
Amount that Bryan has
= 2 u
= $1848
(c)
Amount that Charlie has
= 1 u
= $924
Answer(s): (a) $2068; (b) $1848; (c) $924
