ACT Problem A student has earned the following scores on four 100 -point tests this marking period: 63, 72, 88 and 91. What score must the student earn on the fifth and final 100 -point test of the marking period to earn an average test grade of 80 for the five tests? Now, 63+72+88+91 = 314 Since all the tests are 100 -points, I can find the total of points needed by 5 x 80 = 400 Thus, because 400 – 314 = 86, the student will need 86 points
