The unit selling price p (in dollars) and the quantity demanded x (in pairs) of a certain brand of women’s shoes are given by the demand equation
p(x) = 100e^-0.0001x f or 0 _< x _< 20,000
a. Find the revenue function,R. (Hint: R(x)= x(p(x)), since the
revenue function is the unit selling price at a demand level of x units
times the number of units demanded.)
b. Find the marginal revenue function, R'.
c. What is the marginal revenue when, x = 10 ?
