3 children have a total of $4910.
Bryan has $490 more than Charlie.
Charlie has 6 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 = 6 u
Amount that Bryan has = 6 u + 490
Total amount that Bryan, Charlie and Adam
= 1 u + 6 u + 6 u + 490
= 13 u + 490
13 u + 490 = 4910
13 u = 4910 - 490 = 4420
13 u = 4420
1 u = 4420 ÷ 13 = 340
Amount that Bryan has
= 6 u + 490
= 6 x 340 + 490
= 2040 + 490
= $2530
(b)
Amount that Charlie has
= 6 u
= $2040
(c)
Amount that Adam has
= 1 u
= $340
Answer(s): (a) $2530; (b) $2040; (c) $340
