3 children have a total of $2500.
Charlie has $210 more than Adam.
Adam has 2 times as much as Bryan.
- How much does Charlie have?
- How much does Adam 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 Adam has = 2 u
Amount that Charlie has = 2 u + 210
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 210
= 5 u + 210
5 u + 210 = 2500
5 u = 2500 - 210 = 2290
5 u = 2290
1 u = 2290 ÷ 5 = 458
Amount that Charlie has
= 2 u + 210
= 2 x 458 + 210
= 916 + 210
= $1126
(b)
Amount that Adam has
= 2 u
= $916
(c)
Amount that Bryan has
= 1 u
= $458
Answer(s): (a) $1126; (b) $916; (c) $458
