Find the demand function for the marginal revenue function. Recall that if no items are sold, the revenue is 0 . R(x)=5500.18x Write the integral that is needed to find the revenue function, R(x), where x represents the number of items sold. (5500.18x)dx The revenue function is R(x)=550x0.12x23 Find the demand function for the marginal revenue function. Recall that if no items are sold, the revenue is 0 . R(x)=5500.18x The revenue function is R(x)=550x0.12x23. The demand function for the marginal revenue function R(x)=5500.18x is p=5500.12x21
