Thread: Applications of the derivative/Related Rates

The manufacturer has found that the cost C and revenue R (in dollars) in one month are related by the equation

C= (R^2/450,000)+12,000

Find the rate of change of revenue with respect to time when the cost is changing by $15 per month and the monthly revenue is $25,000

Thx.
