The total revenue from the sale of x stereos is given by upper r left parenthesis x right parenthesis equals 3 comma 000 left parenthesis 1 minus startfraction x over 700 endfraction right parenthesis squared .r(x)=3,0001− x 7002. find the marginal average revenue, upper r overbar prime left parenthesis x right parenthesisr′(x).

For this case we have the following equation:
  
 We must find the derivative of this function.
 The derivative of the function represents the marginal average revenue.
 We have then:
  
 Simplifying:
  
 
 the marginal average revenue is:
 

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
