Question

Jason earned scores of 90 points, 82 points, 95 points, and 86 points on four tests. What is the lowest score he can get on the fifth test and still finish with an average score of 90 points?

95 points
96 points
97 points
98 points

Answer 1

C 97

Explanation:

So you know that average is equal to all the scores added together divided by the amount of tests right? Now you have 5 tests and you need an average of 90 points. Average=scores added together/no. of test

90=x/5

90*5=x

450=x

Now take 450 subtract all your other 4 scores to get your lowest 5th score

450-90-82-95-86=97

You need at least 97 to have an average of 90.

Answer 2

97 points is your answer 3 hope this helps!
