Your final grade in a course is 80% of your current grade, plus 20% of your final exam score. Your current grade is 83 and your goal is to get a final grade of 85% or better. Write and solve an inequality to find the final exam scores that will meet your goal
---------------------------------
EQUATIONS:
fg = 0.8(83) + 0.2*fe
fg >= 0.85
----------------
Substitute for fg to get:
0.8(83) + 0.20fe >= 0.85, where fe is the final exam score.
