Teddy Bower is an outdoor clothing and accessories chain that purchases a line of parkas at $$9$ each from its Asian supplier, TeddySports. Unfortunately, at the time of the order placement, demand is still uncertain: Teddy Bower forecasts that its demand is normally distributed with a mean of $2,100$ and a standard deviation of $1,500.$ Teddy Bower sells these parkas at $$21$ each. Unsold parkas have little salvage value; Teddy Bower simply gives them away to a charity $($and also doesn't collect a tax benefit for the donation$).$ Use Table $13\mathrm{.}4.$

Note: If a part of the question specifies whether to use Table $13\mathrm{.}4,$ or to use Excel, then credit for a correct answer will depend on using the specified method.
