3 children have a total of $3560.
Bryan has $410 more than Adam.
Adam has 3 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 = 3 u
Amount that Bryan has = 3 u + 410
Total amount that Bryan, Adam and Charlie
= 1 u + 3 u + 3 u + 410
= 7 u + 410
7 u + 410 = 3560
7 u = 3560 - 410 = 3150
7 u = 3150
1 u = 3150 ÷ 7 = 450
Amount that Bryan has
= 3 u + 410
= 3 x 450 + 410
= 1350 + 410
= $1760
(b)
Amount that Adam has
= 3 u
= $1350
(c)
Amount that Charlie has
= 1 u
= $450
Answer(s): (a) $1760; (b) $1350; (c) $450
