Assume the M&M model with corporate taxes. The corporate tax rate is 40%. Your firm is currently unlevered with 100% equity. As of now, the value of the firm's equity is $400K, and the firm's cost of capital is 10%. Assume that your firm can borrow at 4% from a bank. Q1) Suppose that you decided to lever up by reducing equity and increasing debt. As a result, your firm now has $250K in debt. Your firm plans to maintain this debt amount forever. What is the present value of the interest tax shield? A. $80K B. $160K C. $40K D. $100K Q2) What is the value of the firm under the new capital structure? (Hint: Use the first M&M proposition with corporate taxes.) A. $400K B. $250K C. $100K D. $500K Q3) What is the market value of equity under the new capital structure? (Hint: Use the balance sheet identity.) A. $400K B. $100K C. $250K D. $500K Q4) What is the cost of equity under the new capital structure? (Hint: Use the second M&M proposition with corporate taxes.) A. 10% B. 8% C. 4% D. 13.6% Q5) What is the WACC under the new capital structure? A. 13.6% B. 4% C. 10% D. 8%

Using Python, create a program in Top-Down Design that lets the user play rock, paper, scissors against the computer. If both players make the same choice, the process is repeated until there is a clear winner. Thus, a tie does not end a game, so multiple gestures might be needed by each player before there is a winner. After each game, prompt the user with a question like: "Do you want to play again (Y/N)?". When they ultimately quit, your program should output the following statistics: - The number of times the human player won - The number of times that the computer won - The percentage of times that the computer won - The average number of "gestures" per game to determine a winner overall the games played Before you start writing your program, (re)read section 6.2 on Problem Solving with Top-Down Design, because I want you to actually design your program. Split your program up into well-defined functions by doing a top-down design and developing a structure chart. When you write your program, be sure to use: - Meaningful variable names with good style (i.e., useCamelCase or use_underscores) - Docstring comments at the start of the program and after the "def"inition of each function, describing what they do - A main function (see lab4 Part C) located at the top of the program with a call to it at the bottom of the file to start execution - Global constants where appropriate with good style (ALL_CAPS_AND_UNDERSCORES).
