3 children have a total of $4880.
Adam has $240 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 + 240
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 240
= 5 u + 240
5 u + 240 = 4880
5 u = 4880 - 240 = 4640
5 u = 4640
1 u = 4640 ÷ 5 = 928
Amount that Adam has
= 2 u + 240
= 2 x 928 + 240
= 1856 + 240
= $2096
(b)
Amount that Bryan has
= 2 u
= $1856
(c)
Amount that Charlie has
= 1 u
= $928
Answer(s): (a) $2096; (b) $1856; (c) $928
