Rachael hands in her 4th exam. the score on her 1st three exams were 75, 95, and 97. What does she need to earn on the 4th exam to average at least a 90 on the 4 exams? Construct an inequality with the varible x representing her 4th exam score, then solve the inequality for x
----------------------------------------------------
(x + 75 + 95 + 97)/4 >= 90
x + 267 >= 360
x => 93
