Mogul oil company will sell $4000$ barrels of oil in $9$ months. Suppose Mogul hedges the risk by selling futures on $4000$ barrels of oil. The current oil futures price is $$21\mathrm{.}6$ dollars per barrel. If in $9$ months the spot price of oil is $$20\mathrm{.}0$ and the futures price is $$21\mathrm{.}0$ per barrel, what is Mogul's effective price of oil per barrel?
