3 children have a total of $3700.
Adam has $250 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 + 250
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 250
= 5 u + 250
5 u + 250 = 3700
5 u = 3700 - 250 = 3450
5 u = 3450
1 u = 3450 ÷ 5 = 690
Amount that Adam has
= 2 u + 250
= 2 x 690 + 250
= 1380 + 250
= $1630
(b)
Amount that Bryan has
= 2 u
= $1380
(c)
Amount that Charlie has
= 1 u
= $690
Answer(s): (a) $1630; (b) $1380; (c) $690
