What type of crazy decimals did you get? Why didn't you share them?\r

document.write( "Let amount of 5% acid to be mixed, be F
\n" );
document.write( "Then amount of 65% acid to be mixed = 42 – F
\n" );
document.write( "Therefore, we get: .05F + .65(42 – F) = .45(42)
\n" );
document.write( ".05F + 27.3 - .65F = 18.9
\n" );
document.write( ".05F - .65F = 18.9 – 27.3 
\n" );
document.write( "- .6F = - 8.4
\n" );
document.write( "F, or amount of 5% acid to be mixed = \"%28-+8.4%29%2F%28-+.6%29\", or \"highlight_green%2814%29\" mL
\n" );
document.write( "Amount of 65% acid to be mixed: 42 – 14, or \"highlight_green%2828%29\" mL
\n" );
document.write( "You can do the check!!
