3 children have a total of $2270.
Adam has $250 more than Charlie.
Charlie has 2 times as much as Bryan.
- How much does Adam have?
- How much does Charlie have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Charlie has = 2 u
Amount that Adam has = 2 u + 250
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 250
= 5 u + 250
5 u + 250 = 2270
5 u = 2270 - 250 = 2020
5 u = 2020
1 u = 2020 ÷ 5 = 404
Amount that Adam has
= 2 u + 250
= 2 x 404 + 250
= 808 + 250
= $1058
(b)
Amount that Charlie has
= 2 u
= $808
(c)
Amount that Bryan has
= 1 u
= $404
Answer(s): (a) $1058; (b) $808; (c) $404
