3 children have a total of $3710.
Charlie has $470 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 + 470
Total amount that Charlie, Adam and Bryan
= 1 u + 4 u + 4 u + 470
= 9 u + 470
9 u + 470 = 3710
9 u = 3710 - 470 = 3240
9 u = 3240
1 u = 3240 ÷ 9 = 360
Amount that Charlie has
= 4 u + 470
= 4 x 360 + 470
= 1440 + 470
= $1910
(b)
Amount that Adam has
= 4 u
= $1440
(c)
Amount that Bryan has
= 1 u
= $360
Answer(s): (a) $1910; (b) $1440; (c) $360
