A profit-maximizing firm will employ one additional unit of a resource if themarginal revenue product of that unit isgreater than the marginal cost of that unit. Suppose a firm uses skilled workers, unskilled workers, and machines in the production of cell phones. Which of the following conditions will be true when the firm minimizes per-unit costs of production? a. MP of Skilled Labor/Price of Skilled Labor > MP of Unskilled Labor/Price of Unskilled Labor > MP of a Machine/Price of a Machine.
b. MP of Skilled Labor/Price of Skilled Labor > MP of Unskilled Labor/Price of Unskilled Labor > MP of a Machine/Price of a Machine.
c. MP of Skilled Labor/Price of Skilled Labor = MP of Unskilled Labor/Price of Unskilled Labor = MP of a Machine/Price of a Machine.
d. MP of Skilled Labor/Price of Skilled Labor = MP of Unskilled Labor/Price of Unskilled Labor > MP of a Machine/Price of a Machine.

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
