3 children have a total of $1180.
Adam has $200 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 + 200
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 200
= 5 u + 200
5 u + 200 = 1180
5 u = 1180 - 200 = 980
5 u = 980
1 u = 980 ÷ 5 = 196
Amount that Adam has
= 2 u + 200
= 2 x 196 + 200
= 392 + 200
= $592
(b)
Amount that Bryan has
= 2 u
= $392
(c)
Amount that Charlie has
= 1 u
= $196
Answer(s): (a) $592; (b) $392; (c) $196
