You can put this solution on YOUR website!
Remember:
\n" ); document.write( "Let $\"X=minutes\"$ , and
\n" ); document.write( " $\"Charge=%28Rate%29%28Minutes%29\"$ , where $\"Rate=0.20%2Fminute\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"14.40=%280.20%2Fminute%29%28X%29\"$
\n" ); document.write( " $\"cross%2814.40%2972%2Fcross%280.20%29=cross%280.20%29X%2Fcross%280.20%29\"$
\n" ); document.write( " $\"X=72Minutes\"$ --------------> minutes used that month
\n" ); document.write( "*Note: if you multiply $\"72Minutes\"$ by $\"rate+=0.20%2Fminute\"$ that equals to $14.40.
