A $40,000 machine will be purchased by a company whose interest rate is 12%. The installation cost is $5,000, and removal costs are insignificant. What is its economic life if its salvage values and O&M costs are as follows? Year 1 => Salvage value = $35,000, O&M cost = $8,000
Year 2 => Salvage value = $30,000, O&M cost = $14,000
Year 3 => Salvage value = $25,000, O&M cost = $20,000
Year 4 => Salvage value = $20,000, O&M cost = $26,000
Year 5 => Salvage value = $15,000, O&M cost = $32,000

Historically, 12 percent of a mail-order firm's repeat charge-account customers have an incorrect current address in the firm's computer database. the number of customers out of 19 who have an incorrect address in the database is a binomial random variable with n = 19 and 2formula36.mml = 0.12.

At cooly cola, we are testing the appeal of our new diet one cola. in a taste test of 250 randomly chosen cola drinkers, 200 consumers preferred diet one cola to the leading brand. assuming that the sample were large enough, the large-sample 95% confidence interval for the population proportion of cola drinkers that prefer diet one cola would be:

Suppose that two firms produce differentiated products and compete in prices. as in class, the two firms are located at two ends of a line one mile apart. consumers are evenly distributed along the line. the firms have identical marginal cost, $60. firm b produces a product with value $110 to consumers.firm a (located at 0 on the unit line) produces a higher quality product with value $120 to consumers. the cost of travel are directly related to the distance a consumer travels to purchase a good. if a consumerhas to travel a mile to purchase a good, the incur a cost of $20. if they have to travel x fraction of a mile, they incur a cost of $20x. (a) write down the expressions for how much a consumer at location d would value the products sold by firms a and b, if they set prices p_{a} and p_{b} ? (b) based on your expressions in (a), how much will be demanded from each firm if prices p_{a} and p_{b} are set? (c) what are the nash equilibrium prices?
