Hi,

If I have a testhighlight_green%28x%29  worth 25% of a grade and I currently have a 70 average, 

what is the minimum score I can receive to achieve an 80% overall or better? 

  .80*70 + .25x   ≥   80

            x ≥   (80-56)/.25

            x  ≥  96,  96 the minimum score to achieve an 80% overall or better
