3 children have a total of $4310.
Charlie has $230 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 + 230
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 230
= 5 u + 230
5 u + 230 = 4310
5 u = 4310 - 230 = 4080
5 u = 4080
1 u = 4080 ÷ 5 = 816
Amount that Charlie has
= 2 u + 230
= 2 x 816 + 230
= 1632 + 230
= $1862
(b)
Amount that Adam has
= 2 u
= $1632
(c)
Amount that Bryan has
= 1 u
= $816
Answer(s): (a) $1862; (b) $1632; (c) $816
