3 children have a total of $4790.
Bryan has $450 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 + 450
Total amount that Bryan, Charlie and Adam
= 1 u + 3 u + 3 u + 450
= 7 u + 450
7 u + 450 = 4790
7 u = 4790 - 450 = 4340
7 u = 4340
1 u = 4340 ÷ 7 = 620
Amount that Bryan has
= 3 u + 450
= 3 x 620 + 450
= 1860 + 450
= $2310
(b)
Amount that Charlie has
= 3 u
= $1860
(c)
Amount that Adam has
= 1 u
= $620
Answer(s): (a) $2310; (b) $1860; (c) $620
