Hi,
If I have a test{{{highlight_green(x)}}}  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   &#8805;   80
            x &#8805;   (80-56)/.25
            x  &#8805;  96,  96 the minimum score to achieve an 80% overall or better
