A buyer for a department store orders sweaters about 6 months before the winter season. The store plans to hold a March clearance sale to sell any surplus goods by February 29. Each piece costs $100 per pair and sells for $120 per pair. At the sale price of $60 per pair, it is expected that any remaining stock can be sold during the March sale. Assume that a uniform probability distribution ranging from 250 to 450 items describes the demand. The expected demand is 300. In the context of the single period inventory system, the optimal order size Qmust satisfy the condition .

a. P(demand ≤ Q*) = 1/4
b. P(demand ≤ Q*) = 1/3
c. P(demand ≤ Q*) = 1/5
d. P(demand ≤ Q*) = 1/2

A) plot the m1 and m2 money stock in the us from 1990-2015. (hint: you may use the data tools provided by fred.) (b) plot the nominal interest rate from 1960 to 2014. (hint: you can either use the daily interest rates for selected u. s. treasury, private money market and capital market instruments from or the effective federal funds rate fromfred.) (c) the consumer price index (cpi) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. intuitively, the cpi represents the cost of living or the average price level. plot the cpi from 1960 to 2013.(d) the inflation rate is the yearly percentage change in the average price level. in practice, we usually use the percentage change in the cpi to compute the inflation rate. plot the inflation rate from 1960 to 2013.(e) explain the difference between the ex-ante and ex-post real interest rate. use the fisher equation to compute the ex-post real interest rate. plot the nominal interest rate and the ex-post real interest rate from 1960 to 2013 in the same graph.
