Sayuri's Asian Café makes the best pot stickers in town. The kitchen's production is usually between 20 and 22 pot stickers per hour. Sayuri buys a new machine to help the team make pot stickers faster. She tracks production over the course of seven days. On which day does the machine make a positive impact on production?

Day 3 Day 4 Day 5 Day 6

I was going to graph this, but I believe that is unnecessary.

Days 1-3 are all within the normal, pre-machine range.

Days 4 and 5 are collectively 15 pot stickers/hr beneath range.

Day 6 is 50, the average is ~20, so we have an excess of 30. This also takes care of the lag in production from days 4 and 5.

So Day 6 is when the machine returns a positive impact.
