Grading scale 1 has the following weights- (tests- 50% quiz- 25% homework- 15% final exam- 10%). calculate your final average if your performance in the class is as follows- test grades- 78 quiz- 87 homework- 80 final exam- 90.

a. 78(50) + 87(25) + 80(15) + 90(10) = x

b. 78(.50) + 87(.25) + 80(.15) + 90(.10) = x

c. 78(5) + 87(2.5) + 80(1.5) + 90(.10) = x

d. 78(50) + 87(.25) + 80(1.5) + 90(.10) = x
