Question

a students course grade is based on one midterm that counts as 10% 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 50% of his final grade. his midterm score is 68, his project score is 82, his homework score is 93, and his final exam score is 79. 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 (type an integer or a decimal. do not round.)

Explanation:

Step1: Calculate weighted scores

Mid - term: $68\times0.1$
Project: $82\times0.05$
Homework: $93\times0.35$
Final exam: $79\times0.5$

Step2: Sum up weighted scores

$68\times0.1 + 82\times0.05+93\times0.35 + 79\times0.5$
$=6.8+4.1 + 32.55+39.5$
$=82.95$

Answer:

$82.95$
