3 children have a total of $4370.
Adam has $210 more than Charlie.
Charlie has 6 times as much as Bryan.
- How much does Adam have?
- How much does Charlie have?
- How much does Bryan have?
(a)
Choose the person with least money to be 1 u.
Amount that Bryan has = 1 u
Amount that Charlie has = 6 u
Amount that Adam has = 6 u + 210
Total amount that Adam, Charlie and Bryan
= 1 u + 6 u + 6 u + 210
= 13 u + 210
13 u + 210 = 4370
13 u = 4370 - 210 = 4160
13 u = 4160
1 u = 4160 ÷ 13 = 320
Amount that Adam has
= 6 u + 210
= 6 x 320 + 210
= 1920 + 210
= $2130
(b)
Amount that Charlie has
= 6 u
= $1920
(c)
Amount that Bryan has
= 1 u
= $320
Answer(s): (a) $2130; (b) $1920; (c) $320
