3 children have a total of $2030.
Adam has $240 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 + 240
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 240
= 5 u + 240
5 u + 240 = 2030
5 u = 2030 - 240 = 1790
5 u = 1790
1 u = 1790 ÷ 5 = 358
Amount that Adam has
= 2 u + 240
= 2 x 358 + 240
= 716 + 240
= $956
(b)
Amount that Bryan has
= 2 u
= $716
(c)
Amount that Charlie has
= 1 u
= $358
Answer(s): (a) $956; (b) $716; (c) $358
