Question 190544: Hockey player recieve 2 points whan they win and 1 point when they tie .One season a team won a champion ship with 57 points. the won 9 more games than they tied. How many did the team have?
Miquel's insurance company will replace his car if repair cost exceed 80% of the cars value. The car recently sustained 7200 woth of damage, but it was not replaceed what was the value of this car?
You can put this solution on YOUR website! Question #1: Hockey
Let x=no of games tied
. x+9=no of games won ("they won 9 more games than they tied")
.
2*(x+9)=no of points for games won
1*x =no of points for games tied
.
The team got 57 points for the season, so:
2*(x+9)+1*x=57
.
Simplifying, we get:
.
Subtracting 18 from both sides, we get:
.
Dividing both sides by 3, we get:
.
The team tied 13 games and won 13+9=22 games
.
.
Question #2:Insurance
.
Let x=value of Miquel's car
80%x or 0.8x=maximum damage cost for the car to be replaced
.
We know that 7200 is less than 80% since the car was not replaced yet, so:
0.8x>7200
.
Dividing both sides by 0.8, we get:
x>9000
.
Therefore, Miquel's car must be worth more than 9000.
