You are taking a class in which your grades are determined from five sources: 50% from your test mean, 15% from your midterm, 20% from your final exam, 10% from your computer lab work, and 5% from your homework. Your scores are 86%(test mean), 96% (midterm), 82%(final exam), 98%(computer lab), and 100%(homework). What is the weighted mean of your scores?
