The manager of big box store has found that if the price of a pillow is p(x)=100-x/8 then x pillows will be sold.
\n" ); document.write( "The expression for the total revenue from the sale of x pillows is
\n" ); document.write( "R(x) = 100x -x^2/8
\n" ); document.write( "Find the number of pillows that will produce maximum revenue.
\n" ); document.write( "------
\n" ); document.write( "R'(x) = 100- (2/8)x
\n" ); document.write( "----
\n" ); document.write( "R'(x) = 100 - (1/4)x
\n" ); document.write( "--------
\n" ); document.write( "Solve: 100-(1/4)x = 0
\n" ); document.write( "x = 400
\n" ); document.write( "-----------------
