The profit on a watch is given by $\"p=x%5E2-13x-80\"$ Where x is the number of watches sold per day. How many watches were sold on a day when there was a $50 loss?
\n" ); document.write( "Since there was a $50 loss, the profit would be -50
\n" ); document.write( " $\"-50+=+x%5E2-13x-80\"$
\n" ); document.write( " $\"0=x%5E2-13x-80%2B50\"$
\n" ); document.write( " $\"0=x%5E2+-+13x-30\"$
\n" ); document.write( "0=(x+2)(x-15)
\n" ); document.write( "x+2=0
\n" ); document.write( "x=-2
\n" ); document.write( "x-15=0
\n" ); document.write( "x=15
\n" ); document.write( "It says they sold some watches, so the answer would need to be 15.
\n" ); document.write( ":) \n" ); document.write( "
