3 children have a total of $3190.
Adam has $120 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 + 120
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 120
= 5 u + 120
5 u + 120 = 3190
5 u = 3190 - 120 = 3070
5 u = 3070
1 u = 3070 ÷ 5 = 614
Amount that Adam has
= 2 u + 120
= 2 x 614 + 120
= 1228 + 120
= $1348
(b)
Amount that Bryan has
= 2 u
= $1228
(c)
Amount that Charlie has
= 1 u
= $614
Answer(s): (a) $1348; (b) $1228; (c) $614
