Let $\"+t+\"$ = time vet spent making house calls
\n" ); document.write( " $\"+2t+\"$ = vets time spent tending animals
\n" ); document.write( " $\"+1+\"$ hours spent eating lunch, so vet worked
\n" ); document.write( " $\"+8+-+1+=+7+\"$ hrs/day
\n" ); document.write( "---------------------
\n" ); document.write( " $\"+t+%2B+2t+=+7+\"$
\n" ); document.write( " $\"+3t+=+7+\"$
\n" ); document.write( " $\"+t+=+7%2F3+\"$ hrs
\n" ); document.write( " $\"+t+=+2+%2B+1%2F3+\"$
\n" ); document.write( "convert $\"+1%2F3+\"$ hr to minutes
\n" ); document.write( " $\"+%281%2F3%29%2A60+=+20+\"$ min
\n" ); document.write( "The vet spent 2 hrs and 20 min making house calls
\n" ); document.write( "check:
\n" ); document.write( " $\"+t+%2B+2t+=+7+\"$
\n" ); document.write( " $\"+7%2F3+%2B+2%2A%287%2F3+%29+=+7+\"$
\n" ); document.write( " $\"+7%2F3+%2B+14%2F3+=+7+\"$
\n" ); document.write( " $\"+21%2F3+=+7+\"$
\n" ); document.write( " $\"+7+=+7+\"$
\n" ); document.write( "OK \n" ); document.write( "
