The price p in dollars and the quantity x sold of a certain product obey the demand equation -1/5x+100 (0≤ x ≤ 500) a) Express the revenue R as a function of x. (remember, R= p. x)

b) What is the revenue if 200 units are sold?

c) What quantity x that maximizes the revenue?

e) What price should the company charge to maximize revenue?

Answer to your question is given in the attachment

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
