Plan A: $300 plus $9.00 per hour;
\n" ); document.write( "Plan B: Straight $12.50 per hour.
\n" ); document.write( "Suppose that the job takes n hours. For what values of n is plan B better for Branford
\n" ); document.write( ":
\n" ); document.write( "cost of plan A= 9x+300. where n is the number of hours worked
\n" ); document.write( ":
\n" ); document.write( "cost of plan B=12.50x
\n" ); document.write( ":
\n" ); document.write( "we are looking for the value of N that makes Plan B better which means we want the cost to be cheaper or less than plan A'
\n" ); document.write( ":
\n" ); document.write( "12.50x<9x+300
\n" ); document.write( ":
\n" ); document.write( "3.5x<300
\n" ); document.write( ":
\n" ); document.write( " $\"x%3C85.71%29\"$
\n" ); document.write( ":
\n" ); document.write( "this means for any thing above 85.71 hours and Plan A will be cheaper.... \n" ); document.write( "

\n" );
