Hey,\r \n" ); document.write( "\n" ); document.write( "For this one, we need to put the cost, C(x), which is 978, into the equation:\r \n" ); document.write( "\n" ); document.write( "978 = .7x + 682\r \n" ); document.write( "\n" ); document.write( "We subract 682 from both sides:\r \n" ); document.write( "\n" ); document.write( "296 = .7x\r \n" ); document.write( "\n" ); document.write( "We then divide both sides by .7:\r \n" ); document.write( "\n" ); document.write( "x = 422.857...\r \n" ); document.write( "\n" ); document.write( "Therefore:\r \n" ); document.write( "\n" ); document.write( "423 units can be produced.\r \n" ); document.write( "\n" ); document.write( "I hope this helps! \n" ); document.write( " |
