Question 1056714
This student's current class grade is 56.56%.
 She has yet to complete one assignment that is 2.14% of the final grade, one assignment that is 2.16% of the final grade, seven assignments that are each .33% of the final grade, and one assignment that is 40% of the final grade.
 If she gets perfect scores on all these assignments, what will the final class grade be?
:
Add up the percents of the class final grade
2.14 + 2.16 + 7(.33) + 40 = 46.61
her grade represents 46.61% of the final grade because she got 100 in all of them
therefore
100 - 46.61 = 53.39% represents the portion of the class that has 56.56%
perhaps we can find the class average this way
av = {{{(46.61(100) + 53.39(56.56))/100}}}
av = {{{(4661 + 3019.74)/100}}}
av = {{{(7680.74)/100}}}
av = 76.81% is the final grade
