3 children have a total of $1060.
Bryan has $100 more than Adam.
Adam has 2 times as much as Charlie.
- How much does Bryan have?
- How much does Adam 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 Adam has = 2 u
Amount that Bryan has = 2 u + 100
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 100
= 5 u + 100
5 u + 100 = 1060
5 u = 1060 - 100 = 960
5 u = 960
1 u = 960 ÷ 5 = 192
Amount that Bryan has
= 2 u + 100
= 2 x 192 + 100
= 384 + 100
= $484
(b)
Amount that Adam has
= 2 u
= $384
(c)
Amount that Charlie has
= 1 u
= $192
Answer(s): (a) $484; (b) $384; (c) $192
