3 children have a total of $3440.
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 = 3440
5 u = 3440 - 110 = 3330
5 u = 3330
1 u = 3330 ÷ 5 = 666
Amount that Charlie has
= 2 u + 110
= 2 x 666 + 110
= 1332 + 110
= $1442
(b)
Amount that Adam has
= 2 u
= $1332
(c)
Amount that Bryan has
= 1 u
= $666
Answer(s): (a) $1442; (b) $1332; (c) $666
