\"A%3C=B\"
\n" ); document.write( "\"20%3C=15%2B0.1%2AN\"
\n" ); document.write( "\"0.1N%3E=5\"
\n" ); document.write( "\"N%3E=50\"
\n" ); document.write( "When the number of calls is greater than or equal to 50, Plan B will be equal to or more expensive than Plan A.
\n" ); document.write( "So then N=49 is the most number of calls you can make and still be cheaper using Plan B.\r
