Homework is worth 10% of my grade, quizzes are worth 30%, and tests are worth 40%. I have 15 grades in the homework section, they''re all 100''s. I have 2 grades in the quiz section, a 75 and an 80. I have 2 grades in the test section, a 51 and a 93. My total average for the class is an 80. How many more 100''s do i have to get in the homework section to boost my average from an 80 to an 82?
