Taking that position, how much money would you make if the dollar appreciated by $1\%$ by the end of August against the current spot rate $($Cash$-$Last row$)?$

You just took a long position on $6-$month corn futures. Each contract is sized at $5,000$ bushels. You have contracted $100$ contracts at a futures price of $$5\mathrm{.}00$ per bushel.

a$.$ What is the initial contract value?

b$.$ If the initial margin requirement is $7\%,$ how much do you need to put into your account to meet this requirement?

c$.$ If the futures price decreases to $$4\mathrm{.}80,$ what is the mark to market adjustment to your account $($does your account increase or decrease$)?$

d$.$ Does the adjustment in c above trigger a margin call $($assume the minimum maintenance margin is $75\%$ of the contract value $x$ the initial margin requirement of $7\%)?$

e$.$ If the answer in d is yes, how much do you need to put into your account to bring it up to the new margin requirement $($at $100\%$ of contract value $7\%)?$
