**MathMate**, Thursday, May 19, 2011 at 9:30amFive tests with an average ≥70 means a total score of ≥ 5*70=350, but < 5*80 = 400.

He has already got:79 + 85 +81 + 65 = 310 points.

What should he get to score (x) between 350 and 400?

350 ≤ 310+x < 400

Subtract 310 from the above inequality to find the range of x.
