3 children have a total of $2670.
Bryan has $360 more than Charlie.
Charlie has 3 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 = 3 u
Amount that Bryan has = 3 u + 360
Total amount that Bryan, Charlie and Adam
= 1 u + 3 u + 3 u + 360
= 7 u + 360
7 u + 360 = 2670
7 u = 2670 - 360 = 2310
7 u = 2310
1 u = 2310 ÷ 7 = 330
Amount that Bryan has
= 3 u + 360
= 3 x 330 + 360
= 990 + 360
= $1350
(b)
Amount that Charlie has
= 3 u
= $990
(c)
Amount that Adam has
= 1 u
= $330
Answer(s): (a) $1350; (b) $990; (c) $330
