3 children have a total of $2130.
Charlie has $240 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 + 240
Total amount that Charlie, Adam and Bryan
= 1 u + 2 u + 2 u + 240
= 5 u + 240
5 u + 240 = 2130
5 u = 2130 - 240 = 1890
5 u = 1890
1 u = 1890 ÷ 5 = 378
Amount that Charlie has
= 2 u + 240
= 2 x 378 + 240
= 756 + 240
= $996
(b)
Amount that Adam has
= 2 u
= $756
(c)
Amount that Bryan has
= 1 u
= $378
Answer(s): (a) $996; (b) $756; (c) $378
