3 children have a total of $4740.
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 = 4740
5 u = 4740 - 480 = 4260
5 u = 4260
1 u = 4260 ÷ 5 = 852
Amount that Adam has
= 2 u + 480
= 2 x 852 + 480
= 1704 + 480
= $2184
(b)
Amount that Charlie has
= 2 u
= $1704
(c)
Amount that Bryan has
= 1 u
= $852
Answer(s): (a) $2184; (b) $1704; (c) $852
