3 children have a total of $2360.
Adam has $220 more than Bryan.
Bryan has 2 times as much as Charlie.
- How much does Adam have?
- How much does Bryan have?
- How much does Charlie have?
(a)
Choose the person with least money to be 1 u.
Amount that Charlie has = 1 u
Amount that Bryan has = 2 u
Amount that Adam has = 2 u + 220
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 220
= 5 u + 220
5 u + 220 = 2360
5 u = 2360 - 220 = 2140
5 u = 2140
1 u = 2140 ÷ 5 = 428
Amount that Adam has
= 2 u + 220
= 2 x 428 + 220
= 856 + 220
= $1076
(b)
Amount that Bryan has
= 2 u
= $856
(c)
Amount that Charlie has
= 1 u
= $428
Answer(s): (a) $1076; (b) $856; (c) $428
