The revenue, in dollars, from the sale of x belts is given by R(x)=40x^4/7 Find the rate at which average revenue is changing when 545 belts have been produced
When 545 belts have been produced and sold, the average revenue is changing at :1) dollars per belt 2) belts per dollar for each additional belt
(Round to four decimal places as needed. Do not include the $ symbol in your answer.)

The average revenue is decreasing at a rate of 0.0021 dollars per belt when 545 belts have been produced and sold.

Step-by-step explanation:

We are given the following in the question:

where R(x) is the revenue function and x is the number of belts.

Average revenue:

Rate of change of average revenue:

Putting x = 545

Thus, when 545 belts have been produced and sold, the average revenue is decreasing at a rate of 0.0021 dollars per belt.
