A retired auto mechanic hopes to open a rustproofing shop. Customers would be local new-car dealers. Two locations are being considered, one in the center of the city and one on the outskirts. The central city location would involve fixed monthly costs of $7,000 and labor, materials, and transportation costs of$30 per car. The outside location would have fixed monthly costs of $4,700 and labor, materials, and transportation costs of$40 per car. Dealer price at either location will be $90 per car. a. Which location will yield the greatest profit if monthly demand is (1) 200 cars? (2) 300 cars? b. At what volume of output will the two sites yield the same monthly profit?

A firm that has recently experienced enormous growth is seeking to lease a small plant in Memphis, TN; Biloxi, MS; or Birmingham, AL. Prepare an economic analysis of the three locations given the following information: Annual costs for building, equipment, and administration would be $40,000 for Memphis,$60,000 for Biloxi, and $100,000 for Birmingham. Labor and materials are expected to be$8 per unit in Memphis, $4 per unit in Biloxi, and$5 per unit in Birmingham. The Memphis location would increase system transportation costs by $50,000 per year, the Biloxi location by$60,000 per year, and the Birmingham location by $25,000 per year. Expected annual volume is 10,000 units.

A small producer of machine tools wants to move to a larger building, and has identified two alternatives. Location A has annual fixed costs of $800,000 and variable costs of$14,000 per unit; location B has annual fixed costs of $920,000 and variable costs of$13,000 per unit. The finished items sell for $17,000 each. a. At what volume of output would the two locations have the same total cost? b. For what range of output would location A be superior? For what range would B be superior?

Social networks involve interactions (connections) between members of the network. Sociologists define network density as the ratio of actual network connections to the number of possible one-to-one connections. For example, a network with 10 members has

$$\left( \begin{array} { c } { 10 } \\ { 2 } \end{array} \right) = 45$$

total possible connections. If that network has only 5 connections, the network density is 5/45 = .111 . Sociologists at the University of Michigan assumed that the density x of a social network would follow a uniform distribution between 0 and 1 ( Social Networks , 2010). What is the probability that the randomly selected network has a density higher than .7?
