3 children have a total of $1660.
Bryan has $220 more than Adam.
Adam has 2 times as much as Charlie.
- How much does Bryan have?
- How much does Adam 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 Adam has = 2 u
Amount that Bryan has = 2 u + 220
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 220
= 5 u + 220
5 u + 220 = 1660
5 u = 1660 - 220 = 1440
5 u = 1440
1 u = 1440 ÷ 5 = 288
Amount that Bryan has
= 2 u + 220
= 2 x 288 + 220
= 576 + 220
= $796
(b)
Amount that Adam has
= 2 u
= $576
(c)
Amount that Charlie has
= 1 u
= $288
Answer(s): (a) $796; (b) $576; (c) $288
