\n" ); document.write( "c = 55h + 20 is the original cost equation
\n" ); document.write( "h = number of hours
\n" ); document.write( "55h = amount of money charged at $55 an hour for h hours (ignoring the $20 surcharge)
\n" ); document.write( "55h+20 = amount of money charged total, including the surcharge\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The plumber raises the hourly rate by $5, so $55 becomes 55+5 = 60 dollars an hour.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The new equation is now c = 60h + 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Plug in h = 2 to find the cost (c) for 2 hours worth of work.
\n" ); document.write( "c = 60h + 20
\n" ); document.write( "c = 60(2) + 20
\n" ); document.write( "c = 120 + 20
\n" ); document.write( "c = 140\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The cost for 2 hours worth of work is $140
\n" ); document.write( " \n" ); document.write( "
\n" );
