Question $1$ options:

The Hudson Bay is planning orders for its summer catalog. One order is to be placed at the beginning of the season. The demand forecast for one of its shirts is normally distributed, with a mean of $5,500$ and standard deviation of $2,200.$ Each shirt is purchased for $$100,$ and any unsold shirts at the end of the season will be discounted and sold through the outlet store for $$70.$ At this price, virtually all shirts are expected to sell. It costs another $$15$ to store an unsold shirt for the season and then move it to the outlet store. The members of the buying committee disagree on the effect of stocking out and the number of shirts to be ordered. One of the members believes that $6,500$ shirts should be ordered, whereas another wants to order $8,500$ jackets

At what cost of stocking out would the order size of $6,500$ be justified? Round your answer to $2$ decimal places.
