document.write( "Hi
\n" );
document.write( "1:30 solution of acetic acid is a .0333% solution or .9777% water
\n" );
document.write( "One would need to dilute the proper amount of 5% solution to achieve this. 
\n" );
document.write( "Let x be the amount of the 5% solution to be used(95% water)
\n" );
document.write( " .95x + (75-x) = .9777*75ml
\n" );
document.write( "     75-.9777*75 = .05x
\n" );
document.write( "         33.45ml = x, the amount 
\n" );
document.write( " 33.45ml of 5% solution would needed to be mixed with 41.55ml of water.\r
\n" );
document.write( "\n" );
document.write( " .95*33.45 + 41.55 = 31.7775 + 41.55 = .9777*75 = 73.3275 \n" );
document.write( "

\n" );
