    At Priscilla's school, the final grade for her Calculus course is weighted as follows: Tests: 50% Quizzes: 30% Homework: 20% Priscilla has an average of 87% on her tests, 100% on her quizzes, and 20% on her homework. What is Priscilla's weighted average?

    Weighted Average gives weights to each percent of the average as follows:
    Weighted Average = Average * weighting percent

    Weighted Average = Test Average * Test Weighting + Quiz Average. * Quiz Weighting + Homework Average * Homework Weighting
    Weighted Average = 87% * 50% + 100% * 30% + 20% * 20%
    Weighted Average = 43.5% + 30% + 4%
    Weighted Average = 77.5%
