A small grocery store sells fresh produce that it obtains daily from a local farmer. During the strawberry season, demand for fresh strawberries can be reasonably approximated using a normal distribution with a mean of $40$ quarts per day and a standard deviation of $6$ quarts per day. The marginal cost of fresh strawberries is $$0\mathrm{.}35$ per quart. The grocer determines that the optimal order quantity is $49$ quarts per day.

What is the marginal benefit $($i$.$e$.,$ cost of shortage$)$ at the optimal order quantity? Please provide your answer in decimal format to two decimal places and without the dollar sign $($e$.$g$.,1\mathrm{.}15,0\mathrm{.}75,0\mathrm{.}20)$
