Hoping to increase his company' s market share, the CEO of QuikFashion has decided to hold a month-long sale in which all of the clothing in QuikFashion' s stores will be discounted by at least 50 percent. Although this discount will mean that the company is selling clothing at cost, the CEO hopes that this broadly advertised sale will attract repeat buyers to QuikFashion, who will return to buy clothing at full price after the month of sales. In assessing the CEO's ability to achieve his goals with this plan, it would be most useful to know which of the following? ["Whether QuikFashion's competitors would respond by discounting their own clothing.", 'Whether some items of clothing will be discounted more than others.', 'Whether QuikFashion can cut the cost of production sufficiently to still make profits from its discounted clothing.', 'Whether following a different plan might allow QuikFashion to maintain its current market share but increase profits.']
