3 children have a total of $3530.
Charlie has $310 more than Bryan.
Bryan has 2 times as much as Adam.
- How much does Charlie have?
- How much does Bryan have?
- How much does Adam have?
(a)
Choose the person with least money to be 1 u.
Amount that Adam has = 1 u
Amount that Bryan has = 2 u
Amount that Charlie has = 2 u + 310
Total amount that Charlie, Bryan and Adam
= 1 u + 2 u + 2 u + 310
= 5 u + 310
5 u + 310 = 3530
5 u = 3530 - 310 = 3220
5 u = 3220
1 u = 3220 ÷ 5 = 644
Amount that Charlie has
= 2 u + 310
= 2 x 644 + 310
= 1288 + 310
= $1598
(b)
Amount that Bryan has
= 2 u
= $1288
(c)
Amount that Adam has
= 1 u
= $644
Answer(s): (a) $1598; (b) $1288; (c) $644
