Let x represent Holly's score on 7th math quiz.
We have been given that the mean of Holly's first six math quiz scores was 75%. This means that the average on 1st 6 math quizzes is 75.
To find the total scores on 1st 6 math quizzes, we will multiply 75 by 6 that is 
.
We will use average formula to find test scores on 7th math quiz.
Let us solve for x.
Therefore, Molly's score on the 7th math quiz was 89.
