3 children have a total of $4190.
Bryan has $120 more than Adam.
Adam has 5 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 = 5 u
Amount that Bryan has = 5 u + 120
Total amount that Bryan, Adam and Charlie
= 1 u + 5 u + 5 u + 120
= 11 u + 120
11 u + 120 = 4190
11 u = 4190 - 120 = 4070
11 u = 4070
1 u = 4070 ÷ 11 = 370
Amount that Bryan has
= 5 u + 120
= 5 x 370 + 120
= 1850 + 120
= $1970
(b)
Amount that Adam has
= 5 u
= $1850
(c)
Amount that Charlie has
= 1 u
= $370
Answer(s): (a) $1970; (b) $1850; (c) $370
