Pat is mixing two sulfuric acid solutions, one 40% and one 10%. To get 15 liters of a solution that is 30%
\n" ); document.write( "sulfuric acid, how much of each must she use?
\n" ); document.write( "----
\n" ); document.write( "f = amount of 40%
\n" ); document.write( "t = amount of 10%
\n" ); document.write( "---
\n" ); document.write( "f + t = 15 --- total solution
\n" ); document.write( "40f + 10t = 15*30 --- total acid
\n" ); document.write( "
\n" ); document.write( "
