You can put this solution on YOUR website!
Two hundred students CONSUME THE FOOD in 50 days; so 1 student consumes THE FOOD in \"200%2A50%2Adays=10000%2Adays\". The one-student rate is \"%281%2F1000%29%28FOOD%2FDAY%29\". This is the key to use.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Two parts make the job of CONSUME THE FOOD.
\n" ); document.write( "200 students for 20 days, and then \"200-50=150\" students for unknown t days.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Again, the job is CONSUME THE FOOD.
\n" ); document.write( "\"200%2A%281%2F10000%29%2A20%2B150%281%2F10000%29%2At=1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2%2F10%2B%2815%2F1000%29t=1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1%2F5%2B3t%2F200=1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"40%2B3t=200\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3t=160\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"t=160%2F3\"
\n" ); document.write( "\"highlight%28t=54%261%2F3%29\", which may mean, fifty-three days and one-third of a day.
\n" ); document.write( "
\n" );
