I need help with Question entire question 3

Question 3 [24] ACB, the manufacturer of a leading microwave brand that can generate low-calorie microwavable food, estimated the following demand equation for its product using data from 26 supermarkets around the country for the month of April: Q = 5 200 - 42P + 20Px + 5.2L + 0.20A + 0.25M (2.002) (17.5) (6.2) (2.5) (0.09) (0.21) R3 = 0.80 I= 26 F = 4 88 Assume the following values for the independent variables: Q = Quantity sold per month P (in cents) = Price of the product = 500 Av Px (in cents) = Price of the leading competitor's product = 600 L (in rands) = Per capita income of the standard metropolitan area (SMSA) in which the supermarket is located = 5 500 A (in rands) = Monthly advertising expenditure = 10 000 M = Number of microwave ovens sold in SMSA in which the supermarket is located = 5 000 3.1. Determine the quantity of microwaves that the company will sell per month. (2) 3.2. Calculate the price and income elasticities for the product. (4) 3.3. What is the meaning of the R? = 0.60? (2) 3.4. Answer the following: 3.4.1. Determine the t-values for the price of the leading competitor's product (X) and advertising expenditure (A). (4) 3.4.2. Are they significant? Why or why not? (4) 3.5. What is the meaning of 5.2L in the equation? (2) 3.6. Assume that the market for microwaves in the SMSA is an oligopoly market with a kinked demand curve as propagated by Paul Sweezy. Given the price of the competitor, graphically illustrate and explain the possible predicament for the company given its price. (6)
