3 children have a total of $2550.
Charlie has $120 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 + 120
Total amount that Charlie, Adam and Bryan
= 1 u + 4 u + 4 u + 120
= 9 u + 120
9 u + 120 = 2550
9 u = 2550 - 120 = 2430
9 u = 2430
1 u = 2430 ÷ 9 = 270
Amount that Charlie has
= 4 u + 120
= 4 x 270 + 120
= 1080 + 120
= $1200
(b)
Amount that Adam has
= 4 u
= $1080
(c)
Amount that Bryan has
= 1 u
= $270
Answer(s): (a) $1200; (b) $1080; (c) $270
