3 children have a total of $3510.
Adam has $130 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 + 130
Total amount that Adam, Bryan and Charlie
= 1 u + 6 u + 6 u + 130
= 13 u + 130
13 u + 130 = 3510
13 u = 3510 - 130 = 3380
13 u = 3380
1 u = 3380 ÷ 13 = 260
Amount that Adam has
= 6 u + 130
= 6 x 260 + 130
= 1560 + 130
= $1690
(b)
Amount that Bryan has
= 6 u
= $1560
(c)
Amount that Charlie has
= 1 u
= $260
Answer(s): (a) $1690; (b) $1560; (c) $260
