3 children have a total of $3590.
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 = 3590
5 u = 3590 - 430 = 3160
5 u = 3160
1 u = 3160 ÷ 5 = 632
Amount that Adam has
= 2 u + 430
= 2 x 632 + 430
= 1264 + 430
= $1694
(b)
Amount that Bryan has
= 2 u
= $1264
(c)
Amount that Charlie has
= 1 u
= $632
Answer(s): (a) $1694; (b) $1264; (c) $632
