3 children have a total of $3860.
Adam has $220 more than Bryan.
Bryan has 6 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 = 6 u
Amount that Adam has = 6 u + 220
Total amount that Adam, Bryan and Charlie
= 1 u + 6 u + 6 u + 220
= 13 u + 220
13 u + 220 = 3860
13 u = 3860 - 220 = 3640
13 u = 3640
1 u = 3640 ÷ 13 = 280
Amount that Adam has
= 6 u + 220
= 6 x 280 + 220
= 1680 + 220
= $1900
(b)
Amount that Bryan has
= 6 u
= $1680
(c)
Amount that Charlie has
= 1 u
= $280
Answer(s): (a) $1900; (b) $1680; (c) $280
