Betty Cooker runs a bakery in San Francisco that specializes in her famous Black Forest cakes. These cakes come with four kinds of frostings: vanilla, chocolate, raspberry and devilicious. She estimates that the daily demand for each type of cake is independent and is normally distributed with a mean of 50 and a standard deviation of 20. Each customer wants to buy exactly one cake. Customers who favor a particular type of frosting will not buy any other if their preferred frosting is out of stock. Every day in the morning, Betty Cooker and her team of bakers bake a fresh batch of the cakes for sale that day. Her costs to bake and top each cake are $5. Each cake sells for $15. Betty's Bakery prides itself on its fresh assortment, so cakes not sold by the end of that day are given away to a soup kitchen for the homeless

A. Suppose Betty wants to bake enough cakes so that she can be 97.5% sure that she can satisfy the demand of all of her customers. How many cakes with devilicious frosting should she prepare daily in the morning? (Enter the answer as a whole number.)

B. She hires a consultant, Trump McDonald, who advises her to, "Focus on maximizing your expected daily profits, and the customer demand will take care of itself." In order to maximize profits, Trump advises Betty to bake 60 Devilicious cakes. What would be Betty's expected profit from Devilicious cakes if she followed Trump's advice? (Round the answer to 2 decimal places.)
