Let the amount of minutes used for option 2 that'll exceed charges for option 1, be m
\n" ); document.write( "Option 1: Cost, or \"C%28m%29+=+%22%24%2249\" for \"m+%3C=+200\"
\n" ); document.write( "Option 2: Cost, or \"C%28m%29+=+.6m+%2B+31\"
\n" ); document.write( "For C(m) for option 2 to exceed C(m) for option 1, we get: \".6m+%2B+31+%3E+49\"
\n" ); document.write( "\".6m+%3E=+49+-+31\"
\n" ); document.write( "\".6m+%3E+18\"
\n" ); document.write( "m, or minutes > \"18%2F.6\", or \"highlight_green%28m+%3E+30%29\"
\n" ); document.write( " \n" ); document.write( "
