Answer:
There are 37 shirts in the batch.
Step-by-step explanation:
Since it takes an initial 4 minutes to set up the screen-printer, we can subtract 4 from 41 minutes to get the time used to print the shirts.
41 - 4 = 37
Since each shirt requires 1 minute of screen printing and there are 37 minutes, we can divide 37 by 1.
37 / 1 = 37
So there are 37 shirts in this batch. Hope this helps.
