3 children have a total of $3320.
Adam has $330 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 + 330
Total amount that Adam, Bryan and Charlie
= 1 u + 6 u + 6 u + 330
= 13 u + 330
13 u + 330 = 3320
13 u = 3320 - 330 = 2990
13 u = 2990
1 u = 2990 ÷ 13 = 230
Amount that Adam has
= 6 u + 330
= 6 x 230 + 330
= 1380 + 330
= $1710
(b)
Amount that Bryan has
= 6 u
= $1380
(c)
Amount that Charlie has
= 1 u
= $230
Answer(s): (a) $1710; (b) $1380; (c) $230
