Hello. Can you please in words explain how you got the answer that you did?
Mr. Imperfecto teaches another math class. This time he has 23 students take a test, the average score on which is an 87. Mr. Imperfecto realizes he put the wrong grade in for a student. He entered a 35, and the score should have been an 85. To the nearest integer, what is the new class average?
That is the first answer I got and it was also marked as incorrect. I am not sure why. I also tried the rounded version and it didn't work.
This question is incorrect, can you please fix it. This is also my last question, so if you cant I would appreciate the question credit back. Thanks!
