3 children have a total of $3290.
Adam has $200 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 + 200
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 200
= 5 u + 200
5 u + 200 = 3290
5 u = 3290 - 200 = 3090
5 u = 3090
1 u = 3090 ÷ 5 = 618
Amount that Adam has
= 2 u + 200
= 2 x 618 + 200
= 1236 + 200
= $1436
(b)
Amount that Charlie has
= 2 u
= $1236
(c)
Amount that Bryan has
= 1 u
= $618
Answer(s): (a) $1436; (b) $1236; (c) $618
