Suppose you bought a bond with an annual coupon rate of 7 percent one year ago for $860. the bond sells for $890 today. a. assuming a $1,000 face value, what was your total dollar return on this investment over the past year? b. what was your total nominal rate of return on this investment over the past year? (do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.) c. if the inflation rate last year was 1.5 percent, what was your total real rate of return on this investment? (do not round intermediate calculations. enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.)

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1

White truffles are a very prized and rare edible fungus that grow naturally in the countryside near alba, italy. suppose that it costs $200 per day to search for white truffles. on an average day, the total number of white truffles (t) found in alba is t = 20x − x 2 , where x is the number of people searching for white truffles on that day. white truffles can be sold for $100 each. if there is no regulation, how many more people will be searching for white truffles than the socially optimal number?
