3 children have a total of $4150.
Adam has $210 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 + 210
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 210
= 5 u + 210
5 u + 210 = 4150
5 u = 4150 - 210 = 3940
5 u = 3940
1 u = 3940 ÷ 5 = 788
Amount that Adam has
= 2 u + 210
= 2 x 788 + 210
= 1576 + 210
= $1786
(b)
Amount that Charlie has
= 2 u
= $1576
(c)
Amount that Bryan has
= 1 u
= $788
Answer(s): (a) $1786; (b) $1576; (c) $788
