Complete the following questions on demand function: 1. Write the demand equation resulting from your output. Include specific coefficients. 2. Calculate the price elasticity of demand for this manufacturer if the price is $9.25 per unit, consumer income is $21,000, advertising is $100,000, and the quantity demanded is $499,999. Is demand elastic or inelastic at this price and quantity? 3. Calculate income elasticity of demand for this manufacturer at the same point as identified in question 2. Is the product an inferior good, a normal good, or a luxury? Must use run regression for #1..excel data is attached:

Total cost = sum of all costs of doing business
Q sold = the quantity sold (in units) that quarter
Q prod = the quantity produced (in units) that quarter
Q dem = the quantity demanded (in units) that quarter
Price = price per unit charged by the firm
Labor = # labor hours used in production in that quarter. For purposes of this assignment, assume that all labor hours are identical.
Capital Investment = the number of plants in operation that quarter. Assume for the sake of this project, that all plants are approximately equal in size and use of technology.
Advertising Expenses = dollars spent on advertising that quarter
Capital Consumer Advertising
