3 children have a total of $2920.
Adam has $230 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 + 230
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 230
= 5 u + 230
5 u + 230 = 2920
5 u = 2920 - 230 = 2690
5 u = 2690
1 u = 2690 ÷ 5 = 538
Amount that Adam has
= 2 u + 230
= 2 x 538 + 230
= 1076 + 230
= $1306
(b)
Amount that Bryan has
= 2 u
= $1076
(c)
Amount that Charlie has
= 1 u
= $538
Answer(s): (a) $1306; (b) $1076; (c) $538
