3 children have a total of $4900.
Bryan has $480 more than Adam.
Adam has 6 times as much as Charlie.
- How much does Bryan have?
- How much does Adam 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 Adam has = 6 u
Amount that Bryan has = 6 u + 480
Total amount that Bryan, Adam and Charlie
= 1 u + 6 u + 6 u + 480
= 13 u + 480
13 u + 480 = 4900
13 u = 4900 - 480 = 4420
13 u = 4420
1 u = 4420 ÷ 13 = 340
Amount that Bryan has
= 6 u + 480
= 6 x 340 + 480
= 2040 + 480
= $2520
(b)
Amount that Adam has
= 6 u
= $2040
(c)
Amount that Charlie has
= 1 u
= $340
Answer(s): (a) $2520; (b) $2040; (c) $340
