3 children have a total of $3640.
Charlie has $110 more than Adam.
Adam has 2 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 = 2 u
Amount that Charlie has = 2 u + 110
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 110
= 5 u + 110
5 u + 110 = 3640
5 u = 3640 - 110 = 3530
5 u = 3530
1 u = 3530 ÷ 5 = 706
Amount that Charlie has
= 2 u + 110
= 2 x 706 + 110
= 1412 + 110
= $1522
(b)
Amount that Adam has
= 2 u
= $1412
(c)
Amount that Bryan has
= 1 u
= $706
Answer(s): (a) $1522; (b) $1412; (c) $706
