eric has unit test scores of 70, 79, 52 and 54 in MATH015. He needs an average of 69.5 or greater to be able to progress to the next class in the math sequence. I final exam counts as 2 tests, write an inequality to find what scores on the final exam eric needs to progree to the next course in the sequence.

avg>=69.5
(70+79+52+54+F+F)/6>=69.5
multipy both sides by 6
then subtract 79+70+52+54 from each side.
then divide each side by 2, solving for F
