Question 270726: An arithmetic student needs an average of 70 or more to receive credit for the course. She scored 82, 64, and 98 on the first three exams. Write an inequality representing the score she must get on the last test to receive credit for the course. Answer by solver91311(24713) (Show Source):
If you need to average 70 for 4 exams, then the total points earned must be 4 times 70 equals 280. If you have already taken 3 tests and scored 82, 64, and 98, then you have scored 82 + 64 + 98 = 244. That means you must score at least 280 - 244 = 36 points on the last exam.
