12 men working 7 hours a day can finish a job in 6 days.
\n" ); document.write( " How many more hours a day must 8 men work in order to finish the job in 7 days?
\n" ); document.write( " What would the equation be?
\n" ); document.write( ":
\n" ); document.write( "Find the number of man-hours required to do the job
\n" ); document.write( "12 * 7 * 6 = 504 man-hrs
\n" ); document.write( ":
\n" ); document.write( "Let m = no. of more hrs per day required for 8 men to do the job in 7 days
\n" ); document.write( ":
\n" ); document.write( "8 * (m+7) * 7 = 504
\n" ); document.write( "8(m+7) * 7 = 504
\n" ); document.write( "7(8m+56) = 504
\n" ); document.write( "56m + 382 = 504
\n" ); document.write( "56m = 112
\n" ); document.write( "m = $\"112%2F56\"$
\n" ); document.write( "m = 2 more hrs a day required
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if this adds up
\n" ); document.write( "8 * 9 * 7 = 504, it does \n" ); document.write( "

\n" );
