Start: 108 liters; 22% solution; amount of alcohol=0.22(108)=23.76 liters \n" ); document.write( "Add: 90 liters; x% solution; amount of alcohol= 90x \n" ); document.write( "End with: 198 liters; 37% solution: amount of alcohol= 0.37(198)= 73.26 liters \n" ); document.write( "EQUATION: \n" ); document.write( "alcohol + alcohol= alcohol \n" ); document.write( "23.76 + 90x = 73.26 \n" ); document.write( "90x=49.5 \n" ); document.write( "x=.55 = 55% \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
