3 children have a total of $2280.
Adam has $300 more than Charlie.
Charlie has 4 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 = 4 u
Amount that Adam has = 4 u + 300
Total amount that Adam, Charlie and Bryan
= 1 u + 4 u + 4 u + 300
= 9 u + 300
9 u + 300 = 2280
9 u = 2280 - 300 = 1980
9 u = 1980
1 u = 1980 ÷ 9 = 220
Amount that Adam has
= 4 u + 300
= 4 x 220 + 300
= 880 + 300
= $1180
(b)
Amount that Charlie has
= 4 u
= $880
(c)
Amount that Bryan has
= 1 u
= $220
Answer(s): (a) $1180; (b) $880; (c) $220
