You can put this solution on YOUR website!
They want you to show the inverse relation
\n" ); document.write( "which is \"+p+=+k%2A%281%2Ft%29+\"
\n" ); document.write( "where
\n" ); document.write( "\"+p+\" = number of painters
\n" ); document.write( "\"+t+\" = hours it takes them to paint a house
\n" ); document.write( "\"+k+\" = constant of proportionality
\n" ); document.write( "------------------------------
\n" ); document.write( "You have to find \"+k+\"
\n" ); document.write( "given:
\n" ); document.write( "\"+4+=+k%2A%281%2F40%29+\"
\n" ); document.write( "\"+160+=+k+\"
\n" ); document.write( "Now you can say:
\n" ); document.write( "\"+10+=+160%2A%281%2Ft%29+\"
\n" ); document.write( "\"+10t+=+160+\"
\n" ); document.write( "\"+t+=+16+\"
\n" ); document.write( "(D) 16 hours is the answer
\n" ); document.write( "
\n" );
