Yellows vary inversely as grays cubed
\n" ); document.write( ":
\n" ); document.write( "Let k = the constant of the variation.

\n" ); document.write( "270 = $\"k%2F2%5E3\"$
\n" ); document.write( "k = 8 * 270
\n" ); document.write( "k = 2160
\n" ); document.write( ":
\n" ); document.write( "How many yellows are present when there are 6 grays?
\n" ); document.write( "y = 2160/6^3
\n" ); document.write( "y = 2160/216
\n" ); document.write( "y = 10\r
