In math class, a student has an average grade of 85% for five tests so far. What grade must that student earn on the next test to reach an average grade of 90% for all six tests?

  1. Ms. Sue

    90 * 6 = 540

    85 * 5 = 425

    540 - 425 = 115

    It can't be done if the maximum grade for a test is 100.
