The number of seats in a football stadium is fixed at 70,000. The team raises the price of a ticket from $30, at which 70,000 are sold, to $40, and it sells 60,000 tickets. Assume a straight-line downward-sloping demand curve. The price change caused a change in the consumer surplus of: Group of answer choices –$650,000 –$10 –$65,000 –$100,000

5.1 Consider the system of equation $Ax = c$, where matrix $\begin{bmatrix} 1 & 0 & 2 \\ 2 & -1 & 3 \\ -1 & 2 & 0 \\ -2 & 1 & -3 \end{bmatrix}$ $A =$ and vector $c = \begin{bmatrix} 2 \\ 2 \\ 5 \\ 0 \end{bmatrix}$. 5.1.1 Find a least squares inverse of A. (6) 5.1.2 Show that the system of equations is inconsistent. (7) 5.1.3 Find a least squares solution. (4) 5.1.4 Is the solution unique? Why or why not? (3) 5.2 Show that $x_*$ is a least squares solution to the system of equations $Ax = c$ if and only if $A^\prime Ax_* = A^\prime c$. (6)

DROP DOWN OPTION: (YES OR NO) month. mall's own time to be high so that the property will be valuable. Therefore, the store has been offered a great deal (owner's words) on a new 5-year lease. The new lease calls for no rent for 9 months, then payments of $2,500 per month for the next 51 months. The lease cannot be broken, and the store's WACC is 12% (or 1% per month). a. Should the new lease be accepted? (Hint: Be sure to use 1% per month.) rqaq suaayipu!

Do not round intermediate calculations. Round your answer to the nearest cent. 5 c. The store owner is not sure of the 12% WACC, it could be higher or lower. At what nominal/WACC would the store owner be indifferent between the two leases? (Hint: Calculate the differences between the two payment streams; then find its IRR.)

Question 2. [16 marks] A country has two oil producers, A and B, whose products are identical and they compete in quantities. Let P denote the oil price, $q_A$ the quantity sold by firm A, and $q_B$ the quantity sold by B. Each firm has a constant marginal cost of $MC_A = MC_B = $6 per pizza. The aggregate demand function for pizza is $Q = 60 - 2P$. a) [6 marks] Derive firm A's best-response function, $q_A = R_A(q_B)$. Also derive firm B's best- response function, $q_B = R_B(q_A)$. b) [7 marks] Solve for the Cournot equilibrium output levels $q_A$ and $q_B$. Sketch the two firms best-response functions (use horizontal axis for $q_A$ and vertical axis for $q_B$). c) [3 marks] Now suppose that firm A's marginal cost has decreased while B's cost does not change. Will firm A produce more or less? Will firm B produce more or less? Sketch this change in the graph in part b).
