To find the least number of saves the goalie, which must be made in each of the remaining games to break the school record.
Answer to Problem 7PTTS
Least number of saves the goalie, which must be made in each of the remaining games to break the school record is 11.
Explanation of Solution
Given information:
A soccer goalie has made 175 saves so far in this season.
The school record is 256 saves in a season and there are six games left to play.
Calculation:
Let
So, total number of saves made by the player in 6 games is
The player already saved 175 saves in this season.
So, total number of saves made by the player at the end of the season is
To break the school record the player must save at least 256 saves in a season.
Therefore,
Total number of saves made by the player at the end of the season is
The inequality is thus obtained as:
Now, solve the inequality,
Hence,
Least number of saves the goalie, which must be made in each of the remaining games to break the school record is 11.
