1). Consider a distillery that produces whisky. The main physical limitation on how much whisky can be made by the distillery is the number of stills in operation (the still is the piece of equipment that actually does the distilling).

Suppose the distillery can produce the following amount of whisky depending on how many stills it uses: (picture below)

2). Calculate the marginal product for each still (give your answer to one decimal):

first still: 3 barrel(s)
fourth still: 3 barrel(s)
sixth still: ____ barrel(s)
eighth still: ____ barrel(s)
