The cost C (in dollars) for a company to make x dozen units of a certain product is given by C = 0.1x^2 + 0.6x + 10. How many units can be made for $60?
\n" ); document.write( "------------------
\n" ); document.write( "60 = 0.1x^2 + 0.6x + 10
\n" ); document.write( "0.1x^2 + 0.6x -50 = 0
\n" ); document.write( "10x^2 + 60x -500 = 0
\n" ); document.write( "x = [-60 +- sqrt(3600 - 4*10*-500)]/20
\n" ); document.write( "x = [-60 +- 153.62..]/20
\n" ); document.write( "x = 4.6811... dozen units
\n" ); document.write( "=============
