Question

What grade does Lamont need to get on the next test to have an average of exactly 90? Explain your answer.

Answer 1

Answer:

94

Step-by-step explanation:

 

$B. \\ -7+4 (-11)+7+6+(-3)=-3+ (-4)+3\\\ = -4$

C. To get an exactly average, Lamont needs to get a 94 on the next test, as it will make the sum of Above/Below 90 row equal to zero.

So, Lamont is exactly 4 points below average 90.
