3 children have a total of $3190.
Adam has $480 more than Charlie.
Charlie has 2 times as much as Bryan.
- How much does Adam have?
- How much does Charlie 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 Charlie has = 2 u
Amount that Adam has = 2 u + 480
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 480
= 5 u + 480
5 u + 480 = 3190
5 u = 3190 - 480 = 2710
5 u = 2710
1 u = 2710 ÷ 5 = 542
Amount that Adam has
= 2 u + 480
= 2 x 542 + 480
= 1084 + 480
= $1564
(b)
Amount that Charlie has
= 2 u
= $1084
(c)
Amount that Bryan has
= 1 u
= $542
Answer(s): (a) $1564; (b) $1084; (c) $542
