3 children have a total of $3010.
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 = 3010
5 u = 3010 - 200 = 2810
5 u = 2810
1 u = 2810 ÷ 5 = 562
Amount that Adam has
= 2 u + 200
= 2 x 562 + 200
= 1124 + 200
= $1324
(b)
Amount that Bryan has
= 2 u
= $1124
(c)
Amount that Charlie has
= 1 u
= $562
Answer(s): (a) $1324; (b) $1124; (c) $562
