A student's course grade is based on one midterm that counts as 1010 % of his final grade, one class project that counts as 1515 % of his final grade, a set of homework assignments that counts as 4040 % of his final grade, and a final exam that counts as 3535 % of his final grade. His midterm score is 6767 , his project score is 8888 , his homework score is 9191 , and his final exam score is 7272. What is his overall final score? What letter grade did he earn (A, B, C, D, or F) ? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on.

His overall final score is 81.5

He earned a B

Step-by-step explanation:

To find his overall grade, we multiply each of his grades by it's weight.

Grades:

67 on the midterm, which counts for 10% = 0.1

88 on the project, which counts for 15% = 0.15

91 on homework assignements, which counts for 40% = 0.4

72 on the final exam, which counts for 35% = 0.35.

What is his overall final score?

67*0.1 + 88*0.15 + 91*0.4 + 72*0.35 = 81.5

His overall final score is 81.5

At least 80 and less than 90 has a letter grade of B. 81.5 is in this range. So he earned a B
