A student's course grade is based on one midterm that counts as 10% of his final grade, one class project that counts as 25% of his final grade, a set of homework assignments that counts as 50% of his final grade, and a final exam that counts as 15% of his final grade. his midterm score is 74, his project score is 93, his homework score is 83, 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.

Overall Final Score = 83.7

Letter Grade = B

Step-by-step explanation:

To calculate weighted marks (grade), the rule is to multiply each weight  (in decimal) with respective marks and add them together. Let's do this:

Overall final score = (0.10*74) + (0.25*93) + (0.50*83) + (0.15*77) = 83.7

From the information given, we know that score between 80 and 90 is a "B".
