Question

A​ student's course grade is based on one midterm that counts as 5​% of his final​ grade, one class project that counts as 15​% of his final​ grade, a set of homework assignments that counts as 35​% of his final​ grade, and a final exam that counts as 45​% of his final grade. His midterm score is 75​, his project score is 93​, his homework score is 78​, and his final exam score is 70. 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

Answer:

• 76.5
• C

Step-by-step explanation:

Apply the weights to the scores and add them up:

  5% × midterm + 15% × project + 35% × homework + 45% × final

  = 0.05(75) +0.15(93) +0.35(78) +0.45(70)

  = 76.5

The student has a solid letter grade of C.
