3 children have a total of $2680.
Adam has $370 more than Charlie.
Charlie has 2 times as much as Bryan.
- How much does Adam have?
- How much does Charlie have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Charlie has = 2 u
Amount that Adam has = 2 u + 370
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 370
= 5 u + 370
5 u + 370 = 2680
5 u = 2680 - 370 = 2310
5 u = 2310
1 u = 2310 ÷ 5 = 462
Amount that Adam has
= 2 u + 370
= 2 x 462 + 370
= 924 + 370
= $1294
(b)
Amount that Charlie has
= 2 u
= $924
(c)
Amount that Bryan has
= 1 u
= $462
Answer(s): (a) $1294; (b) $924; (c) $462
