\n" );
document.write( "Hi,
\n" );
document.write( "Annual profit in 'thousands of dollars' is given by the function, P(x)=12x-100
\n" );
document.write( "where 'x is the number of items sold in thousands', x greater than or equal to 10.
\n" );
document.write( "As it pertains to business:
\n" );
document.write( " the $12 is the profit for each x-thousands of items sold)
\n" );
document.write( " the 100(or $100,000 would be the cost of doing business)
\n" );
document.write( "Note P(8) = 12*8-100 =  -4 (or a loss of $4000)
\n" );
document.write( "3. Find the profit for 5 different values of x
\n" );
document.write( "P(10) = 12*10-100 = 20  Pt(10,20)
\n" );
document.write( "P(12) = 12*12-100 = 44  Pt(12,44)
\n" );
document.write( "P(16) = 12*16 - 100 = 92 etc
\n" );
document.write( " \n" );
document.write( "

\n" );
