The figure shows graphs of the marginal revenue function R ' and the marginal cost function C ' for a manufacturer. (Recall from Section 4.7 that R(x) and C(x) represent the revenue and cost when x units are manufactured. Assume that R and C are measured in thousands of dollars.)
R'(x) is above C'(x) between x=50 and x=100
Use the Midpoint Rule to estimate the value of this quantity in thousands of dollars.
