I hope this isn't a real life example!
\n" ); document.write( "Let the final equal: x
\n" ); document.write( "The grade is found by 2/3*midterm+1/3*final.
\n" ); document.write( "She got a 48 on the midterm.
\n" ); document.write( "She wants a score between 70 and 79.
\n" ); document.write( " $\"70%3C%282%2F3%29%2A48%2B%281%2F3%29%2Ax%3C79\"$

\n" ); document.write( "Ask yourself if this seems reasonable. 2/3's of her grade was a 48. It does seam unlikely that she can bring her grade up at least 22 points with only 1/3 of a grade left.
\n" ); document.write( "Wendy is going to need a lot of bonus points! \n" ); document.write( "
