Suppose that you are taking a course where the total class grade is the weighted average of your homework, worksheets, quizzes and tests. The homework is worth 15% of the course grade, worksheets are worth 20% of the course grade, the quizzes are worth 25% of the course grade, and tests are worth 40% of the course grade. To get a B in the course, you must have an overall average of at least 80%. Your current grades in each category are: Homework = 7575%, Worksheets = 7474%, and Quizzes = 6868%. What is the minimum test average you need to get a B in the course?. Your answer is:              %   (Round to at least 1 decimal place)

Question

Suppose that you are taking a course where the total class grade is the weighted average of your homework, worksheets, quizzes and tests.
The homework is worth 15% of the course grade, worksheets are worth 20% of the course grade, the quizzes are worth 25% of the course grade, and tests are worth 40% of the course grade. To get a B in the course, you must have an overall average of at least 80%.

Your current grades in each category are:

Homework = 7575%, Worksheets = 7474%, and Quizzes = 6868%.

What is the minimum test average you need to get a B in the course?.

Your answer is:              %   (Round to at least 1 decimal place)

Expert Solution
Step 1

The homework is worth 15% of the course grade

The worksheets are worth 20% of the course grade

The quizzes are worth 25% of the course grade

The tests are worth 40% of the course grade.

To get a grade B in the course, you must have an overall average of at least 80%.

Current grades in each category are: Homework 75%, worksheets 20%, Quizzes 68%

We have to find the minimum test average you need to get a grade B in the course.
