3 children have a total of $4260.
Adam has $220 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 + 220
Total amount that Adam, Charlie and Bryan
= 1 u + 2 u + 2 u + 220
= 5 u + 220
5 u + 220 = 4260
5 u = 4260 - 220 = 4040
5 u = 4040
1 u = 4040 ÷ 5 = 808
Amount that Adam has
= 2 u + 220
= 2 x 808 + 220
= 1616 + 220
= $1836
(b)
Amount that Charlie has
= 2 u
= $1616
(c)
Amount that Bryan has
= 1 u
= $808
Answer(s): (a) $1836; (b) $1616; (c) $808
