Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
Let = the time in minutes
to screen-print 1 shirt
Let = number of shirts screen-printed
in minutes
-------------------------------
In terms of units:
[ total minutes ] / [ minutes / shirt ] = [ number of shirts ]

----------------------------

It takes 32 min
---------------------
check:
total min printing
[ min/shirt ] x [ number of shirts ] = [ total min ]

OK
