The inventor of a new product charges $4 per unit.
\n" ); document.write( "Her profit for producing and selling x units given by the function:
\n" ); document.write( "P(x)= 2.25x-7000
\n" ); document.write( "A) When x = 2000, Profit P(2000) = (2.25)*2000-7000
\n" ); document.write( " = 4500-7000
\n" ); document.write( " = -2500
\n" ); document.write( " So there is a loss of 2500$
\n" ); document.write( "B)When x = 5000, Profit P(2000) = (2.25)*5000-7000
\n" ); document.write( " = 11250-7000
\n" ); document.write( " = 4250
\n" ); document.write( " So there is a profit of 4250$
\n" ); document.write( "C. What is the break even point for sales
\n" ); document.write( "To get the break even point we have P(x) = 0
\n" ); document.write( " 2.25x-7000=0
\n" ); document.write( " 2.25x = 7000
\n" ); document.write( " x = 7000/225
\n" ); document.write( " x = 31 nearly
\n" ); document.write( "
\n" ); document.write( "
\n" );
