Exchange Rates and WACC problems

See Attached.

1) Suppose 1 Danish krone can be purchased in the spot market for $0.14 today. If the krone appreciated against the dollar by 10% tomorrow, how many krones would a dollar buy tomorrow?

2) Suppose one British pound can purchase 1.82 U.S. dollars today in the foreign exchange market, and currency forecasters predict that the U.S. dollar will depreciate by 12.0% against the pound over the next 30 days. How many dollars will a pound buy in 30 days?

3) Suppose DeGraw Corporation, a U.S. exporter, sold a solar heating station to a Japanese customer at a price of 143.5 million yen, when the exchange rate was 140 yen per dollar. In order to close the sale, DeGraw agreed to make the bill payable in yen, thus agreeing to take some exchange rate risk for the transaction. The terms were net 6 months. If the yen fell against the dollar such that one dollar would buy 154.4 yen when the invoice was paid, what dollar amount would DeGraw actually receive after it exchanged yen for U.S. dollars?

4) Which of the following is NOT a capital component when calculating the weighted average cost of capital (WACC)?

a. Long-term debt.

b. Accounts payable.

c. Retained earnings.

d. Common stock

e. Preferred stock.

5) Hettenhouse Company's perpetual preferred stock sells for $102.50 per share, and it pays a $9.50 annual dividend. If the company were to sell a new preferred issue, it would incur a flotation cost of 4.00% of the price paid by investors. What is the company's cost of preferred stock for use in calculating the WACC (represented as a %)?

6) You were hired as a consultant to Kroncke Company, whose target capital structure is 40% debt, 10% preferred, and 50% common equity. The after-tax cost of debt is 6.00%, the cost of preferred is 7.50%, and the cost of retained earnings is 13.25%. The firm will not be issuing any new stock. What is its WACC (%)?
