Please help me solve this question.\r
\n" ); document.write( "\n" ); document.write( "One canned juice drink is 25% orange juice; another is 5% orange juice. How many liters of each should be mixed together in order to get 20L that is 8% orange juice?
\n" ); document.write( "Let x=liters of 25% solution needed
\n" ); document.write( "Then 20-x=liters of 5% solution needed
\n" ); document.write( "Now we know that the pure orange juice that exists before the mixture takes place (0.25x+0.05(20-x)) has to equal the pure orange juice that exists after the mixture takes place (0.08*20).
\n" ); document.write( "Sooooo
\n" ); document.write( "0.25x+0.05(20-x)=0.08*20
\n" ); document.write( "0.25x+1-0.05x=1.6
\n" ); document.write( "0.20x=0.6
\n" ); document.write( "x=3 liters -----amount of 25% solution needed
\n" ); document.write( "20-x=20-3=17 liters amount of 5% solution needed
\n" ); document.write( "Hope this helps----ptaylor
