After four-point tests, you have 365 points.
a. How many points do you need to score on your next 100-point test to have a mean score of 92 points?
---
Let the next test score be "x".
Solve (365+x)/5 = 92
x = 95
-----------------------------
b. Would a mean score of 92 points after 5 tests be greater than or less than the mean score after four tests?
4-test mean = 365/4 = 91.25

c. Your score on each test is a whole number. Is it possible that your mean score does not change after the fifth test? Explain.
Yes.
