You can put this solution on YOUR website!
x = number of premium channels
\n" ); document.write( "y = total cost
\n" ); document.write( "---
\n" ); document.write( "y = 8.95x + 39.95
\n" ); document.write( "---
\n" ); document.write( "66.80 = 8.95x + 39.95
\n" ); document.write( "8.95x = 66.80 - 39.95
\n" ); document.write( "x = (66.80 - 39.95)/8.95
\n" ); document.write( "x = 3
