Question

Screen-printing a batch of shirts requires 1 minute per shirt in addition to 5 minutes of initial set-up time. If it takes 44 minutes to screen-print a batch of shirts, how many shirts are in the batch?

Answer 1

The problem is a linear equation

of the form y= ax + b

because every shirt requires 1 minute, that means a=1

and because there are 5 minutes more,that means b=5

so the equation is y = x + 5

which value is y? The problem says its 44 minutes, all the amount of time

so we have 44 = x + 5
