Austin Cаnisters Austin Cаnisters mаnufactures decоrative tins that can hоld pоpcorn, cookies, and candy. There are three steps involved in making the tins. First, the decorative patterns are printed on the cut piece of metal, a step called lithography. There is one lithography machine, operated by Amy. This machine requires a 40-minute setup of the inks and patterns before it can process a batch of tins, and then takes a minute per tin to print the patterns. After that, the sheet of metal is molded into a cylinder and sealed at the seams by a machine operated by Bin. This machine requires no setup and takes 4 minutes per tin. Finally, the pre-made bottoms are attached to the cylinder, completing the tin. The machine that attaches the bottoms is operated by Carlos. Prior to working on each batch, the correct size bottoms must be loaded into the machine feeder and the machine needs to be calibrated to the correct size. This setup takes 70 min per batch, and then the machine takes 1.5 minutes per tin. Because each batch varies slightly in shape and pattern, the same batch size is used at both the lithography step and at the bottom attaching step.  The goal is to advise Austin Canisters on what batch size to use, as well as whether they should invest in new technology. 1. What is the capacity of lithography (Amy) (measured in tins per hour) if Austin Canisters works with a batch size of 80 tins? Report your answer in tins/hour.
