3 children have a total of $4870.
Adam has $380 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 + 380
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 380
= 5 u + 380
5 u + 380 = 4870
5 u = 4870 - 380 = 4490
5 u = 4490
1 u = 4490 ÷ 5 = 898
Amount that Adam has
= 2 u + 380
= 2 x 898 + 380
= 1796 + 380
= $2176
(b)
Amount that Bryan has
= 2 u
= $1796
(c)
Amount that Charlie has
= 1 u
= $898
Answer(s): (a) $2176; (b) $1796; (c) $898
