3 children have a total of $3670.
Adam has $310 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 + 310
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 310
= 5 u + 310
5 u + 310 = 3670
5 u = 3670 - 310 = 3360
5 u = 3360
1 u = 3360 ÷ 5 = 672
Amount that Adam has
= 2 u + 310
= 2 x 672 + 310
= 1344 + 310
= $1654
(b)
Amount that Bryan has
= 2 u
= $1344
(c)
Amount that Charlie has
= 1 u
= $672
Answer(s): (a) $1654; (b) $1344; (c) $672
