3 children have a total of $2700.
Charlie has $110 more than Bryan.
Bryan has 3 times as much as Adam.
- How much does Charlie have?
- How much does Bryan have?
- How much does Adam have?
(a)
Choose the person with least money to be 1 u.
Amount that Adam has = 1 u
Amount that Bryan has = 3 u
Amount that Charlie has = 3 u + 110
Total amount that Charlie, Bryan and Adam
= 1 u + 3 u + 3 u + 110
= 7 u + 110
7 u + 110 = 2700
7 u = 2700 - 110 = 2590
7 u = 2590
1 u = 2590 ÷ 7 = 370
Amount that Charlie has
= 3 u + 110
= 3 x 370 + 110
= 1110 + 110
= $1220
(b)
Amount that Bryan has
= 3 u
= $1110
(c)
Amount that Adam has
= 1 u
= $370
Answer(s): (a) $1220; (b) $1110; (c) $370
