I have a 10-ounce glass of kool-aid that is 30% sugar. I want to make it less sweet. How much water can I add to the 30% solution to make it only 25% sugar.
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of water required to make it to reduce the sugar to 25%
\n" ); document.write( ":
\n" ); document.write( "A simple equation:
\n" ); document.write( ".30(10) = .25(x+10)
\n" ); document.write( ":
\n" ); document.write( "3 = .25x + 2.5
\n" ); document.write( ":
\n" ); document.write( "3 - 2.5 = .25x
\n" ); document.write( ":
\n" ); document.write( ".5 = .25x
\n" ); document.write( "x = $\".5%2F.25\"$
\n" ); document.write( "x = 2 oz of water required
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution:
\n" ); document.write( ".3(10) = .25(2+10)
\n" ); document.write( "3 = .25(12); confirms our solution \n" ); document.write( "

\n" );
