Problem 3: Betty and Bob buy a photo from Bertha. They wish to make three payments one at 4 months, the next at 6 months, and the last at 12 months from now. The payment at 6 months should be 50% of the payment at 4 months and the payment at 12 months should be 150% of the payment at 6 months. If they all value the photo at $6,000 now then algebraically find how much each payment should be; based on a 15% per annum simple interest rate? Problem 4: Betty and Bob are short 200 shares of XYZ @48 and long 5 October 50 calls @3. Analyze the value, W, and P&L, Y, of this position at expiration. Be sure to include formulae for W and Y. Be sure to include a table for W and Y at expiration for exercise prices with 5 point intervals. Be sure to draw the graph of Y versus X, the stock price. Algebraically detemiine the break-even points. Problem 5: Problem 22 from Problem Set 1 in Section 8 of Day Of The Quants. Be sure to include a table analysis. Problem 6: Consider a table of financial data as ner I__I_ -2_-I_ such that a
