3 children have a total of $3030.
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 = 3030
5 u = 3030 - 230 = 2800
5 u = 2800
1 u = 2800 ÷ 5 = 560
Amount that Adam has
= 2 u + 230
= 2 x 560 + 230
= 1120 + 230
= $1350
(b)
Amount that Bryan has
= 2 u
= $1120
(c)
Amount that Charlie has
= 1 u
= $560
Answer(s): (a) $1350; (b) $1120; (c) $560
