An entrepreneur wishes to determine if it would be profitable to sell souvenir T$-$shirts at a $2-$night rock concert. The shirts would cost $$3$ each, and booth space and exclusive rights can be obtained for a fee of $$4,000$ for the weekend. The concert is already sold out for both nights, $12,000$ tickets each night. Past experience has shown that approximately $1$ in $10$ ticket holders buys a shirt. If the sales price of the shirts is $$8$ each, how many T$-$shirt in total will have to be sold to generate a pretax operating income of $$1,000$ per night $($i$.$e$.,$ $$2,000$ for the concerts$)?$

$1\mathrm{.}400$ shirts

$1\mathrm{.}200$ shirts

$2\mathrm{.}400$ shirts

$11\mathrm{.}200$ shirts
