\n" ); document.write( "by mixing together a 75% SALINE SOLUTION AND A 55% saline solution.
\n" ); document.write( "Let x and (10qt-x) represent the amount of 75% and 55% solutions respectively
\n" ); document.write( " \"75x+%2B+55%2810-x%29+=+63%2A10\" | After multiplying thru by 100
\n" ); document.write( " 20x = 80
\n" ); document.write( " x = 4qt of 75% and 6qt of 55% (10-4)
\n" ); document.write( "CHECKING our answer***
\n" ); document.write( " \"75%2A4+%2B+55%2A6+=+63%2A10+=+630\" \n" ); document.write( "
