A student's course grade is based on one midterm that counts as 20 % of his final grade, one class project that counts as 5 % of his final grade, a set of homework assignments that counts as 35 % of his final grade, and a final exam that counts as 40 % of his final grade. His midterm score is 63 , his project score is 97 , his homework score is 85 , 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 297. (Type an integer or a decimal rounded to one decimal place as needed.)

78 C

Step-by-step explanation:

The weighted average of the student's scores is ...

0.20*63 + 0.05*97 + 0.35*85 + 0.40*77 = 78

The student's overall final score is 78.

__

The letter grade earned is between 70 and 80, so is a C.
