Let's assume we have speculators who hear about drought damage to the nation's com crop and decide they want to trade com futures. A broker is contacted, the necessary forms are completed, and a speculator is told the margin requirement for a $5,000-$bushel com contract is on the CBOT are $$1,200$ initial and $$800$ maintenance per contract.

$(1)$ Our speculator puts in an order to go long a $5,000-$bushel contract of December com futures at $$3\mathrm{.}50,$ and the order to go long at $$3\mathrm{.}50$ is filled on July $2^{nd}.$

$(2)$ Our speculator puts in an order to go short the same December com futures at $$3\mathrm{.}90$ on July $27,$ and the order to go short at $$3\mathrm{.}90$ is filled in the same day.

Please fill in the last two columns of the following table.
