3 children have a total of $2940.
Bryan has $110 more than Adam.
Adam has 2 times as much as Charlie.
- How much does Bryan have?
- How much does Adam 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 Adam has = 2 u
Amount that Bryan has = 2 u + 110
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 110
= 5 u + 110
5 u + 110 = 2940
5 u = 2940 - 110 = 2830
5 u = 2830
1 u = 2830 ÷ 5 = 566
Amount that Bryan has
= 2 u + 110
= 2 x 566 + 110
= 1132 + 110
= $1242
(b)
Amount that Adam has
= 2 u
= $1132
(c)
Amount that Charlie has
= 1 u
= $566
Answer(s): (a) $1242; (b) $1132; (c) $566
