A company can charge a price of 78 dollars per unit when they sell 440 units. If the price increases by 2 dollars then the number of units that they sell drops by 5. The revenue function for this company is as follows: R(x) = (78 + 2x)(410 - 51) where x is the number of additional units sold beyond 440. Use the Product Rule to find the derivative of R(I) R'(I) = Simplify your answer! Question Help: Message instructor
