You can put this solution on YOUR website! Tests are worth a total of 400pts, quizzes are worth a total of 100pts, homework is worth a total of 50pts and the final is worth 150pts. The total for the semester is 700pts.
TESTS-85,78,62,93.: Average is 79.5%; 0.795(400)=318 pts
QUIZZES-100,85,68,45,93,75,75,65,90,100.: Average =79.6%; 0.796(100)= 79.6 pts
HOMEWORK-100,100,95,90,85,82,83,73,72,100,
100,100,89,50,45,100,91,56,20,78.: Average = 80.45%; 0.8045(50)=40.225 pts
FINAL-82% : .82(150)= 123 pts.
Adding the points you get 560.825
Divide that by 700 to get the final percentage or grade:
You get 80.12 %
