you have a 69 which represents 80% of your grade.
\n" ); document.write( "the final represents 20% of your grade.
\n" ); document.write( "69 * .80 + x * .20 = 77
\n" ); document.write( "simplify to get:
\n" ); document.write( "55.2 + .20x = 77
\n" ); document.write( "subtract 55.2 from both sides of the equation to get:
\n" ); document.write( ".20x = 77 - 55.2 which results in:
\n" ); document.write( ".20x = 21.8
\n" ); document.write( "divide both sides of the equation by .20 to get:
\n" ); document.write( "x = 21.8 / .20 = 109.
\n" ); document.write( "you need a 109 on the final to make at least 77 in the class.
\n" ); document.write( "
