3 children have a total of $3570.
Charlie has $240 more than Adam.
Adam has 4 times as much as Bryan.
- How much does Charlie have?
- How much does Adam 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 Adam has = 4 u
Amount that Charlie has = 4 u + 240
Total amount that Charlie, Adam and Bryan
= 1 u + 4 u + 4 u + 240
= 9 u + 240
9 u + 240 = 3570
9 u = 3570 - 240 = 3330
9 u = 3330
1 u = 3330 ÷ 9 = 370
Amount that Charlie has
= 4 u + 240
= 4 x 370 + 240
= 1480 + 240
= $1720
(b)
Amount that Adam has
= 4 u
= $1480
(c)
Amount that Bryan has
= 1 u
= $370
Answer(s): (a) $1720; (b) $1480; (c) $370
