Assume you own a churro stand. Also assume the next unit of labor that you hire produces 16 churros per hour, and the next machine you could buy makes 21 churros per hour, Assuming you were seeking to expand churro production, which should you as a profit-maximizing firm hire next

Not enough information because the cost of each resource is not given.

Explanation:

With regards to the question, there's no enough information given in order to know the factor to hire next as a profit-maximizing firm.

Even though from the question given, the machine can make more churros per hour than the next unit of labor, the coat of both resources isn't given, therefore we cannot be certain on which one to choose.

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."

hope this : )
