3 children have a total of $1410.
Adam has $360 more than Bryan.
Bryan has 3 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 = 3 u
Amount that Adam has = 3 u + 360
Total amount that Adam, Bryan and Charlie
= 1 u + 3 u + 3 u + 360
= 7 u + 360
7 u + 360 = 1410
7 u = 1410 - 360 = 1050
7 u = 1050
1 u = 1050 ÷ 7 = 150
Amount that Adam has
= 3 u + 360
= 3 x 150 + 360
= 450 + 360
= $810
(b)
Amount that Bryan has
= 3 u
= $450
(c)
Amount that Charlie has
= 1 u
= $150
Answer(s): (a) $810; (b) $450; (c) $150
