Example Question #84 : Mean
Peter scored a 50 and an 80 on his first two exams. There are only four exams in his class and the highest possible score on his exam is a 100. What is the minimum score that Peter must make on his third exam to ensure that he will have a chance to pass the class with an average of 70 after Peter takes his fourth exam?
Set up an equation such that the average of all four scores equal to 70.
Let 
Multiply both sides by four and simplify the numerator.
Subtract 130 on both sides.
Notice that we are looking for Peter's minimum third score that he must make to have a chance at passing the class. The maximum score that Peter can make on his fourth test is 100 and cannot be higher.
Substitute 100 for the y-variable, which represents Peter's fourth test.
Subtract 100 from both sides.
This means that if Peter scored a 50 or higher, he will have a chance of passing the class. Any lower than 50 on his third test will require a score higher than 100 on his fourth test, which is not possible, and Peter will fail the class regardless of what he makes on his fourth test.
The answer is:
Example Question #273 : Algebra Ii
