3 children have a total of $2870.
Bryan has $150 more than Charlie.
Charlie has 2 times as much as Adam.
- How much does Bryan have?
- How much does Charlie 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 Charlie has = 2 u
Amount that Bryan has = 2 u + 150
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 150
= 5 u + 150
5 u + 150 = 2870
5 u = 2870 - 150 = 2720
5 u = 2720
1 u = 2720 ÷ 5 = 544
Amount that Bryan has
= 2 u + 150
= 2 x 544 + 150
= 1088 + 150
= $1238
(b)
Amount that Charlie has
= 2 u
= $1088
(c)
Amount that Adam has
= 1 u
= $544
Answer(s): (a) $1238; (b) $1088; (c) $544
