Question

A​ student's course grade is based on one midterm that counts as 20​%

of his final​ grade, one class project that counts as 25​%

of his final​ grade, a set of homework assignments that counts as 45​%

of his final​ grade, and a final exam that counts as 10​%

of his final grade. His midterm score is

60​,

his project score is

90​,

his homework score is 92​,

and his final exam score is 78.

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.

Answer 1

Overall final score = 60*0.20 + 90*0.25 + 92*0.45 + 78*0.10 = 83.7

Letter grade = B
