3 children have a total of $1820.
Bryan has $440 more than Charlie.
Charlie has 2 times as much as Adam.
- How much does Bryan have?
- How much does Charlie 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 Charlie has = 2 u
Amount that Bryan has = 2 u + 440
Total amount that Bryan, Charlie and Adam
= 1 u + 2 u + 2 u + 440
= 5 u + 440
5 u + 440 = 1820
5 u = 1820 - 440 = 1380
5 u = 1380
1 u = 1380 ÷ 5 = 276
Amount that Bryan has
= 2 u + 440
= 2 x 276 + 440
= 552 + 440
= $992
(b)
Amount that Charlie has
= 2 u
= $552
(c)
Amount that Adam has
= 1 u
= $276
Answer(s): (a) $992; (b) $552; (c) $276
