Question

What must the sum of Latoya’s nine scores be for her to earn an average test score of 93?

Eight of Latoya’s Nine weekly scores
(100 96 90 95 95 100 88 98)
Explain your answer

Answer 1

744

Explanation:

First, you have to find the mean (average) of all the current scores of Latoya. (add all numbers together and divide by the number of values) The sum of all the numbers is 762, so I just kept decreasing the sum until dividing it by 8 gets the quotient of an average test score of 93. So, the answer is 744.
