Let $\"+t+\"$ = the time in minutes
\n" ); document.write( "to screen-print 1 shirt
\n" ); document.write( "Let $\"+n+\"$ = number of shirts screen-printed
\n" ); document.write( "in $\"+t+\"$ minutes
\n" ); document.write( "-------------------------------
\n" ); document.write( "In terms of units:
\n" ); document.write( "[ total minutes ] / [ minutes / shirt ] = [ number of shirts ]
\n" ); document.write( " $\"+n+=+%28+t-16+%29%2F%284%2F3%29++\"$
\n" ); document.write( " $\"+n+=+%28+3%2F4+%29%2A%28+t+-+16+%29+\"$
\n" ); document.write( " $\"+n+=+%283%2F4%29%2At+-+12+\"$
\n" ); document.write( "----------------------------
\n" ); document.write( " $\"+n+=+12+\"$
\n" ); document.write( " $\"+12+=+%283%2F4%29%2At+-+12+\"$
\n" ); document.write( " $\"+%28+3%2F4+%29%2At+=+24+\"$
\n" ); document.write( " $\"+3t+=+96+\"$
\n" ); document.write( " $\"+t+=+32+\"$
\n" ); document.write( "It takes 32 min
\n" ); document.write( "---------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+32+-+16+=+16+\"$ total min printing
\n" ); document.write( "[ min/shirt ] x [ number of shirts ] = [ total min ]
\n" ); document.write( " $\"+%28+4%2F3%29%2A12+=+16+\"$
\n" ); document.write( "OK\r
