Algebra.Com's Answer #79516 by oberobic(2304)![]() ![]() ![]() You can put this solution on YOUR website! You say that press-n-seal costs .5 (1/2) cent per sqft, or $0.005 per sqft.\r \n" ); document.write( "\n" ); document.write( "Press-n-Seal sells for 10/3 the price of Glad Wrap.\r \n" ); document.write( "\n" ); document.write( "How much is Glad Wrap per sq ft?\r \n" ); document.write( "\n" ); document.write( "Let GW = price of Glad Wrap, and PnS = price of Press-n-Seal.\r \n" ); document.write( "\n" ); document.write( "From these few facts, we can derive an equation: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "We are told that \n" ); document.write( "so we know that \n" ); document.write( " \n" ); document.write( "Multiply through by the reciprocal of 10/3 to isolate GW. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So Glad Wrap costs .15 cents per sq ft. \n" ); document.write( "ALWAYS check your work! \n" ); document.write( "We know that 10/3 = 3 1/3. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Check! \n" ); document.write( " \n" ); document.write( " |
