3 children have a total of $1160.
Adam has $210 more than Bryan.
Bryan has 2 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 = 2 u
Amount that Adam has = 2 u + 210
Total amount that Adam, Bryan and Charlie
= 1 u + 2 u + 2 u + 210
= 5 u + 210
5 u + 210 = 1160
5 u = 1160 - 210 = 950
5 u = 950
1 u = 950 ÷ 5 = 190
Amount that Adam has
= 2 u + 210
= 2 x 190 + 210
= 380 + 210
= $590
(b)
Amount that Bryan has
= 2 u
= $380
(c)
Amount that Charlie has
= 1 u
= $190
Answer(s): (a) $590; (b) $380; (c) $190
