Question

By​ studying, Will can produce a higher​ grade, ​, on an upcoming economics exam. His production function depends on the number of hours he studies marginal analysis​ problems, A, and the number of hours he studies supply and demand​ problems, R. ​Specifically,

Gw = 2.5A^0.36R^(0.64)
His roommate​ David's grade-production function is
2.5A^0.25R^(0.75)
Note that d​/dR and d​/dR. ​Will's marginal productivity of studying supply and demand problems is:_____.
a. 1.60A^0.36R^-0.36.
b. 0.64(GW/R).
c. 2.5A^0.36R%0.64/R.
d. both a and b.
e. all of the above.

Answer 1

c. 2.5A^0.36R%0.64/R.

Step-by-step explanation:

Marginal productivity is the increase in amount of one unit of output with the one unit increase of input. Will can produce higher grade when he studies more hours. His grade will increase by one level when he studies more. His grade production function is the level of increase in his output.
