A student's course grade is based on one midterm that counts as 20 % of his final grade, one class project that counts as 20 % of his final grade, a set of homework assignments that counts as 30 % of his final grade, and a final exam that counts as 30 % of his final grade. His midterm score is 64 , his project score is 80 , his homework score is 94 , and his final exam score is 77. 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 80.1.

His letter grade is a B.

Step-by-step explanation:

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

Grades and weights:

His midterm score is 64 . The midterm counts 20% = 0.2.

His project score is 80 . The project score counts 20% = 0.2.

His homework score is 94. The homework score counts 30%.

His final exam score is 77. It counts 30%.

What is his overall final score?

64*0.2 + 80*0.2 + 94*0.3 + 77*0.3 = 80.1

His overall final score is 80.1.

What letter grade did he earn (A, B, C, D, or F) ?

At least 80 but less than 90 is a B. He scored 80.1, so his letter grade is a B.
