Requirements a a 1. Calculate the gross profit of the HDTV at the regular sales price and at the discounted sales price. 2. Assume that during the November/December holiday season last year, Best Buy sold an average of 150 of this particular HDTV per store. If the HDTVs are marked down to $650, how many would each store have to sell this year to make the same total gross profit as last year? 3. Relative to Sales Revenue, what type of costs would Best Buy have that are fixed? What type of costs would be variable? 4. Because Best Buy stated that its cost structure is largely fixed in nature, what might be the impact on operating income if sales decreased? Does having a cost structure that is largely fixed in nature increase the financial risk to a company? Why or why not? 5. Is advertising for Best Buy a fixed or variable cost? If the company has a small margin of safety, how would increasing advertising costs affect Best Buy's operating income? What would be the effect of decreasing advertising costs?

The company is also known for its Geek Squad for technology services. Suppose Best Buy is considering a particular HDTV for a major sales item for Black Friday, the day after Thanksgiving, known as one of the busiest shopping days of the year. Assume the HDTV has a regular sales price of $900, a cost of $500, and a Black Friday proposed discounted sales price of $650.
