3 children have a total of $1670.
Adam has $430 more than Bryan.
Bryan has 2 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 = 2 u
Amount that Adam has = 2 u + 430
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 430
= 5 u + 430
5 u + 430 = 1670
5 u = 1670 - 430 = 1240
5 u = 1240
1 u = 1240 ÷ 5 = 248
Amount that Adam has
= 2 u + 430
= 2 x 248 + 430
= 496 + 430
= $926
(b)
Amount that Bryan has
= 2 u
= $496
(c)
Amount that Charlie has
= 1 u
= $248
Answer(s): (a) $926; (b) $496; (c) $248
