The amount of regular coffee sold was 5 lb more than the amount of decaffeinated coffee sold. There were twice as many pounds of flavored coffee sold than there was regular coffee sold. \n" ); document.write( "a. Write an equation to solve for the amount of regular coffee sold. \n" ); document.write( "r + d + f = 115 \n" ); document.write( "r = d + 5 \n" ); document.write( "f = 2r \n" ); document.write( "----------------- \n" ); document.write( "Substitute to solve for r: \n" ); document.write( "r + (r-5) + 2r = 115 \n" ); document.write( "4r = 120 \n" ); document.write( "r = 30 lbs (amount of regular coffee) \n" ); document.write( "================================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
