Answer:
His overall final score is 81.5
He earned a B
Step-by-step explanation:
To find his overall grade, we multiply each of his grades by it's weight.
Grades:
67 on the midterm, which counts for 10% = 0.1
88 on the project, which counts for 15% = 0.15
91 on homework assignements, which counts for 40% = 0.4
72 on the final exam, which counts for 35% = 0.35.
What is his overall final score?
67*0.1 + 88*0.15 + 91*0.4 + 72*0.35 = 81.5
His overall final score is 81.5
At least 80 and less than 90 has a letter grade of B. 81.5 is in this range. So he earned a B
