Question 8

Solve the problem.
Paul has grades of 68 and 90 on his first two tests. What must he score on his third test in
order to have an average of at least 70?
at most 70
O at least 52
at most 76
O at least 79

Answer 1

At least 52

Explanation:

Paul's current average is a 79. It wouldn't be any of the "at most" answers because the question is looking for an average of "at least" 70. And "at least 79" wouldn't be correct because he could get much less than a 79 and still have an overall average of 70. The answer is at least 52. Hope this helps! Good luck.
