Mogul oil refinery is planning to buy $5000$ barrels of oil in $9$ months. Suppose Mogul hedges the risk by buying futures on $3500\mathrm{.}0$ barrels of oil. The current oil futures price is $$20\mathrm{.}3$ dollars per barrel. If in $9$ months the spot price of oil is $$18\mathrm{.}5$ and the futures price is $$18\mathrm{.}6$ per barrel, what is Mogul's effective cost per barrel?
