Screen printing a batch of shirts takes 0.4 minutes to make a shirt in addition to 4 minutes of initial set time. if it take 6.4 minutes to screen-print a batch of shirts , how many shirts are in the batch?

6 shirts

Step-by-step explanation:

We need to subtract initial set time from 6.4

So,

6.4 - 4 = 2.4 minutes for batch of shirt

Each shirt takes 0.4 minutes and we have 2.4 minutes. Thus number of shirts is:

2.4 / 0.4 = 6 shirts

We have taken 4 minutes as initial time for any number of shirts.
