Consider a monopolistically competitive market with N firms. Each firm's business opportunities are described by the following equations: Demand: Q=160N−P Marginal Revenue: MR=160N−4Q Total Cost: TC=150+Q2 Marginal Cost: MC=4Q As N rises, the demand for each firm's product . How many units does each firm produce? 20N 20 1,280N 20N What price does each firm charge? 140N 140N 180N 160N How much profit does each firm make? 2,800N2 3,200N2−150 150+400N2 2,400N2−150 In the long run, firms will exist in this market.

Bonds often pay a coupon twice a year. for the valuation of bonds that make semiannual payments, the number of periods doubles, whereas the amount of cash flow decreases by half. using the values of cash flows and number of periods, the valuation model is adjusted accordingly. assume that a $1,000,000 par value, semiannual coupon us treasury note with three years to maturity has a coupon rate of 3%. the yield to maturity (ytm) of the bond is 7.70%. using this information and ignoring the other costs involved, calculate the value of the treasury note:
