3 children have a total of $1540.
Bryan has $190 more than Charlie.
Charlie has 2 times as much as Adam.
- How much does Bryan have?
- How much does Charlie have?
- How much does Adam have?
(a)
Choose the person with least money to be 1 u.
Amount that Adam has = 1 u
Amount that Charlie has = 2 u
Amount that Bryan has = 2 u + 190
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 190
= 5 u + 190
5 u + 190 = 1540
5 u = 1540 - 190 = 1350
5 u = 1350
1 u = 1350 ÷ 5 = 270
Amount that Bryan has
= 2 u + 190
= 2 x 270 + 190
= 540 + 190
= $730
(b)
Amount that Charlie has
= 2 u
= $540
(c)
Amount that Adam has
= 1 u
= $270
Answer(s): (a) $730; (b) $540; (c) $270
