Bailey, Kaylee, Haley, and Joyce are four sorority sisters who discovered an opportunity to buy an Internet café. To make the purchase, each of the women would have to put up $$ 80,000. The café's revenue is expected to remain stable at $225,000 per year for the foreseeable future. The costs of running the café (excluding the opportunity costs of the investment). $$

Doug's farm in Idaho has four major fields that he uses to grow potatoes. The productivity of each field follows:

Assume each field is the same size and the variable costs of farming \are $\$25,000$ per year per field. The variable costs cover labour and rented machinery time. Doug must decide how many fields to plant each year. Potato farmers received $6.35 per 100 pounds in 2009. Doug planted how many fields? Explain. Potato prices had dropped to$4.50 per 100 pounds by 2011. How will the price reduction affect Doug's decision? What effect will it have on his labour demand? What effect will it have on the value of Doug's land?

Each month, 25,000 chickens are produced at the Smythe chicken farm south of Little Rock, Arkansas. Smythe Farm's production costs total $28,000. There are two more farms down the road. The monthly output of 55,000 hens at Faubus Farm costs a total of$50,000. Mega Farm spends $91,000 to produce 100,000 chickens each month. These findings imply that the production of chickens benefits significantly from economies of scale. Are you in agreement or disagreement with this claim? Describe your response.
