Can anyone answer these problems for me please!

b. Assume that S&P MidCap 400 futures contracts are priced at $500 X the index and are currently being quoted at 769.40. How many contracts wou1d the Pernellis is have to buy (or sell) toset up the hedge?1.

Given that a $16,875 margin deposit is required to buy or sell a single S&P 400 futurecontract, what would be the Pernellis return On invested capital if the price of the futurescontract changed by the amount computed in question bi?C.
