The spot exchange rate for United States dollars per United Kingdom pound (CNY/USD) is 6.88. If 60-day interest rates are 1.89% in the United States and 4.71% in China, and interest rate parity holds, the 60-day forward CNY/USD exchange rate should be: 6.9122 CNY/USD 6.8753 CNY/USD 6.9289 CNY/USD

The course staff is going out to dinner next week to celebrate, and because the staff is so large and everyone's palates so varied, we've converged on a restaurant that serves lots and lots of different appetizers---21 of them, in fact. Of course, being the probability geeks we are, we plan on rolling a fair, 6-side die 21 times to determine how many servings of each appetizer to order. To put all this in more formal terms, we'll let the total number of servings across all appetizers be modeled by a random variable $T$ which takes on whatever value you get when the 21 independent die rolls are added together. Your final answers should not be in terms of random variables. a. Define $D$ to be the sum of the 21 numbers, minus the value of the highest roll and the value of the lowest roll. What is $E[D]$? (Hint: there's an easy way to derive the result without a lot of algebra.) Let $t$ be your answer to part (a) (Answer $E[T] = \frac{21}{6} = 3.5$). You can leave your answer in terms of $t$ and other numerical terms.

2. Assume that the equation for the demand for bread at a small bakery is $Q^d = 75 - 10P_b + 3Y$, where $Q^d$ is the quantity of bread demanded in loaves, $P_b$ is the price of bread in dollars per loaf, and $Y$ is the average income in the town in thousands of dollars. Assume also that the equation for the supply of bread is $Q^s = 35 + 20P_b - 30P_f$, where $Q^s$ is the quantity supplied, and $P_f$ is the price of flour in dollars per pound. Assume finally that markets clear, so that $Q^d = Q^s$. a. If Y is 10 and $P_f$ is $1, mathematically, determine the equilibrium Q and $P_b$. b. If the average income in the town increases to 15, mathematically, determine the new equilibrium Q and $P_b$.
