Kevin will take 4 math tests this term. All of the tests are worth the same number of points. After taking the first 3 tests, his mean test score is 88 points. How many points does he need on his last test to raise his mean test score to 90 points?



Answer :

Assuming all his scores were the same the first three tests, Kevin will have to score at least a 96 out of a hundred points, if the tests are worth 100 points.
