Question

(08.05)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?

Answer 1

The answer is 97%

Explanation:

Answer 2

If he'll have 5 tests and the average is 90, this means that the scores of each test added must be equal to 90 * 5 or 450.

450 = 90 + 82 + 95 + 86 + x

450 = 353 + x

97 = x which means that he must get a 97% on the fifth test to have an average of 90%
