A textile manufacturer has made an agreement to deliver 100,000 t-shirts in 2 months. There is a concern that the price of cotton, which is the main material used in manufacturing, may fluctuate considerably during the following months. It is estimated that 0.10 kg of cotton will be needed to manufacture each t-shirt. Currently, the spot price of cotton is C0=20$/kg and standard deviation of the cotton price is $2. It is also known that the price of silk is correlated with the cotton. The current price of silk is S0=$50/kg and the standard deviation of the silk price is $4. The correlation coefficient between the cotton price and the silk price is given as 0.80. Assume that the monthly interest rate is 10% per year compounded continuously. The manufacturer wants to hedge his risk against unexpected increases in the price of cotton
