3 children have a total of $3760.
Adam has $470 more than Bryan.
Bryan has 3 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 = 3 u
Amount that Adam has = 3 u + 470
Total amount that Adam, Bryan and Charlie
= 1 u + 3 u + 3 u + 470
= 7 u + 470
7 u + 470 = 3760
7 u = 3760 - 470 = 3290
7 u = 3290
1 u = 3290 ÷ 7 = 470
Amount that Adam has
= 3 u + 470
= 3 x 470 + 470
= 1410 + 470
= $1880
(b)
Amount that Bryan has
= 3 u
= $1410
(c)
Amount that Charlie has
= 1 u
= $470
Answer(s): (a) $1880; (b) $1410; (c) $470
