A person weighting 160 lbs burns 73 calories dancing for 20 minutes
\n" ); document.write( "-------------
\n" ); document.write( "If calories burned is directly related to length of exercise you
\n" ); document.write( "get an equation: cals burned = k(minutes of excercise)
\n" ); document.write( "-----------------
\n" ); document.write( "You need to find \"k\"; substitute the data and solve for \"k\", as follows:
\n" ); document.write( "73 = k(20)
\n" ); document.write( "k = 73/20
\n" ); document.write( "--------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "cals burned = (73/20)(minutes of exercise)
\n" ); document.write( "or, using \"c\" for cals burned and \"e\" for minutes of exercise you get:
\n" ); document.write( "c = (73/20)e
