3 children have a total of $2300.
Adam has $210 more than Bryan.
Bryan has 5 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 = 5 u
Amount that Adam has = 5 u + 210
Total amount that Adam, Bryan and Charlie
= 1 u + 5 u + 5 u + 210
= 11 u + 210
11 u + 210 = 2300
11 u = 2300 - 210 = 2090
11 u = 2090
1 u = 2090 ÷ 11 = 190
Amount that Adam has
= 5 u + 210
= 5 x 190 + 210
= 950 + 210
= $1160
(b)
Amount that Bryan has
= 5 u
= $950
(c)
Amount that Charlie has
= 1 u
= $190
Answer(s): (a) $1160; (b) $950; (c) $190
