\n" ); document.write( "--------------
\n" ); document.write( "Equation:
\n" ); document.write( "iodine + iodine = iodine
\n" ); document.write( "0.18x + 0*40 = 0.10(x+40)
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "18x + 0 = 10x + 10*40
\n" ); document.write( "8x = 10*40
\n" ); document.write( "x = 10*5
\n" ); document.write( "x = 50 quarts (amt. of 18% solution needed in the mixture)
