Answer all parts of this question
(a) Suppose you, as a UK based investor, have an obligation to repay $150 million in nine months time. The current exchange rate is $1.71= £1. UK interest rates are currently quoted at 3% for 6 months and 4% for 9 month loans. The corresponding US rates are 7% and 5%.
(i) What is the appropriate forward rate for your 9-month exposure?

用公式算1.71*（1+5%）/(1+4%)= 1.726=1.73
(ii) Discuss whether the 9-month futures price will differ from the forward rate calculated in i)

futures price 和远期的有什么区别呢

(iii) Based on current values, at what price would you expect forward contracts for delivery after 3 months to be trading in six months time?
这个问是不是只是把利率改成六个月的，算法同第一问呢

Suppose you had bought the forward contract for nine months and, after 6, realised that you no longer needed the contract.
Discuss how you would use a futures contract to eliminate the exposure and the economic and cash flow consequences of this
decision

这个问完全没用思路，不知道该怎么算？
谢谢 望各位指教
