Use this price model to answer question 1-2 below. Revenue Model Use the price model above to construct a revenue model. Find a model for the weekly revenue, using * as the independent variable. NOTE: Do not calculate another regression. Use the price equation to find a model for revenue R(a) = p . x. R(a = p . x = (at bax+ ca2 Use this revenue model to answer questions 3-8 below.Question 3 3 pts Use the revenue model above to answer this question. What is a?
