Answer:
it would take 65 hours to produce all of the order.
Step-by-step explanation:
1. you already would figure out that 26 hours=4 cases or 6.5 hours per case of hairbrushes.
2. You would figure out that 26+26 is 52 so 52 hours for 8 cases
3. Then you remember u have 8 cases of hairbrushes now. Set up a mental equation where you can solve in your mind: if I need 10 cases, but have figured out I only calculated 8, how much more would I still need to meet the order?
4. After mentally solving the hypothetical problem, you then would conclude you needed 2 more cases from 8 to equal 10.
5. you then divide 26 hours per 4 cases and you get 13 hours for 2 cases.
6. finally you multiply 26+26+13 which you would get 65 as the answer
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.
