3 children have a total of $3800.
Adam has $170 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 + 170
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 170
= 5 u + 170
5 u + 170 = 3800
5 u = 3800 - 170 = 3630
5 u = 3630
1 u = 3630 ÷ 5 = 726
Amount that Adam has
= 2 u + 170
= 2 x 726 + 170
= 1452 + 170
= $1622
(b)
Amount that Charlie has
= 2 u
= $1452
(c)
Amount that Bryan has
= 1 u
= $726
Answer(s): (a) $1622; (b) $1452; (c) $726
