3 children have a total of $2180.
Adam has $290 more than Bryan.
Bryan has 3 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 = 3 u
Amount that Adam has = 3 u + 290
Total amount that Adam, Bryan and Charlie
= 1 u + 3 u + 3 u + 290
= 7 u + 290
7 u + 290 = 2180
7 u = 2180 - 290 = 1890
7 u = 1890
1 u = 1890 ÷ 7 = 270
Amount that Adam has
= 3 u + 290
= 3 x 270 + 290
= 810 + 290
= $1100
(b)
Amount that Bryan has
= 3 u
= $810
(c)
Amount that Charlie has
= 1 u
= $270
Answer(s): (a) $1100; (b) $810; (c) $270
