3 children have a total of $2630.
Charlie has $290 more than Bryan.
Bryan has 4 times as much as Adam.
- How much does Charlie have?
- How much does Bryan have?
- How much does Adam have?
(a)
Choose the person with least money to be 1 u.
Amount that Adam has = 1 u
Amount that Bryan has = 4 u
Amount that Charlie has = 4 u + 290
Total amount that Charlie, Bryan and Adam
= 1 u + 4 u + 4 u + 290
= 9 u + 290
9 u + 290 = 2630
9 u = 2630 - 290 = 2340
9 u = 2340
1 u = 2340 ÷ 9 = 260
Amount that Charlie has
= 4 u + 290
= 4 x 260 + 290
= 1040 + 290
= $1330
(b)
Amount that Bryan has
= 4 u
= $1040
(c)
Amount that Adam has
= 1 u
= $260
Answer(s): (a) $1330; (b) $1040; (c) $260
