For the following problems assume the effective 6-month interest rate is 2%, the S&R 6-month forward price is $1020, and use these premiums for S&R options with 6 months to expiration:

Strike	Call	Put
950	120.405	51.777
1000	93.809	74.201
1020	84.47	84.47
1050	71.802	101.214
1107	51.873	137.167

2. What should it cost to implement the strategy from the previous question?

3. What is the implied effective 6-month interest rate from the box spread? (decimal form)
