3 children have a total of $3310.
Bryan has $450 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 + 450
Total amount that Bryan, Adam and Charlie
= 1 u + 2 u + 2 u + 450
= 5 u + 450
5 u + 450 = 3310
5 u = 3310 - 450 = 2860
5 u = 2860
1 u = 2860 ÷ 5 = 572
Amount that Bryan has
= 2 u + 450
= 2 x 572 + 450
= 1144 + 450
= $1594
(b)
Amount that Adam has
= 2 u
= $1144
(c)
Amount that Charlie has
= 1 u
= $572
Answer(s): (a) $1594; (b) $1144; (c) $572
