A professor determines a final grade based on attendance, two papers, three major tests, and a final exam. Each of these activities has a total of 100 possible points. However, the activities carry different weights. Attendance is worth 6%, each paper is worth 8%, each test is worth 19%, and the final is worth 21%. (a) What is the average for a student with 84 on attendance, 78 on the first paper, 89 on the second paper, 68 on test 1, 80 on test 2, 95 on test 3, and 81 on the final exam?
