There seems to be an error in the question. Based on your profit function, there are no values @ 80,000 between x = 0 and x = 50. If you meant, however, 800,000, we are in business.\r
\n" ); document.write( "\n" ); document.write( "Our profit function must = 800,000. So,\r
\n" ); document.write( "\n" ); document.write( "\"-45x%5E3%2B2500x%5E2-275000+=+800000\"\r
\n" ); document.write( "\n" ); document.write( "We set our function = 0 and estimate\r
\n" ); document.write( "\n" ); document.write( "\"-45x%5E3%2B2500x%5E2-1075000+=+0\"\r
\n" ); document.write( "\n" ); document.write( "x = 31.5379 gives us a profit of ~ $800,000.51.\r
\n" ); document.write( "\n" ); document.write( "Now if you selling something, we would have to measure in integer units.
