Algebra.Com's Answer #837047 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Let number of hot dogs sold be x\r \n" ); document.write( "\n" ); document.write( "Revenue = 16.50 x\r \n" ); document.write( "\n" ); document.write( "Rent = $ 75 per night\r \n" ); document.write( "\n" ); document.write( "Income = revenue - expenditure \n" ); document.write( "9.60 /hot dog variable cost\r \n" ); document.write( "\n" ); document.write( "=16.50 x -75 - 9.60x\r \n" ); document.write( "\n" ); document.write( "= 6.90x -75 \n" ); document.write( "6.90x=75 \n" ); document.write( "x= 10.8 hot dogs\r \n" ); document.write( "\n" ); document.write( "11 hot dogs to break even\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
