Answer 1

Let x = number of shirts

Total time to print shirts = time per shirt x number of shirts + set up time

41.71 = 0.98(x)+14.27 Subtract 14.27 from both sides of the equation

41.71-14.27 = 0.98(x)+14.27-14.27 Simplify

27.44=0.98x Divide both sides of the equation by 0.98

27.44/0.98=0.98x/0.98

x=28

There are 28 shirts in the batch
