Worldwide annual sales of a device in 2012–2013 were approximately q = −6p + 3,050 million units at a selling price of $p per unit. Assuming a manufacturing cost of $40 per unit, what selling price would have resulted in the largest annual profit? HINT [See Example 3, and recall that Profit = Revenue − Cost.] (Round your answer to two decimal places.)

Companies hd and ld are both profitable, and they have the same total assets (ta), total invested capital, sales (s), return on assets (roa), and profit margin (pm). both firms finance using only debt and common equity. however, company hd has the higher total debt to total capital ratio. which of the following statements is correct? a) company hd has a higher assets turnover than company ld. b) company hd has a higher return on equity than company ld. c) none of the other statements are correct because the information provided on the question is not enough. d) company hd has lower total assets turnover than company ld. e) company hd has a lower operating income (ebit) than company ld

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
