Jake scored 269 points on three math tests. To get an A for the class, his average number of points on four tests must be no less than 90. If Jake hopes to get an A, how many points must he score on the fourth te
90x4 would be 360. You are calculating average so if he scored 269 in total for 3 tests, and he wants a 90 average, you would do 360-269 which gives you 91. Therefore, he would have to score 91 points on his fourth test.
