3 children have a total of $4140.
Bryan has $110 more than Charlie.
Charlie has 6 times as much as Adam.
- How much does Bryan have?
- How much does Charlie have?
- How much does Adam have?
(a)
Choose the person with least money to be 1 u.
Amount that Adam has = 1 u
Amount that Charlie has = 6 u
Amount that Bryan has = 6 u + 110
Total amount that Bryan, Charlie and Adam
= 1 u + 6 u + 6 u + 110
= 13 u + 110
13 u + 110 = 4140
13 u = 4140 - 110 = 4030
13 u = 4030
1 u = 4030 ÷ 13 = 310
Amount that Bryan has
= 6 u + 110
= 6 x 310 + 110
= 1860 + 110
= $1970
(b)
Amount that Charlie has
= 6 u
= $1860
(c)
Amount that Adam has
= 1 u
= $310
Answer(s): (a) $1970; (b) $1860; (c) $310
