What is a supply function? Think in the same product you presented for question two and provide the supply function for it with 5 specific variables. 6 .

At that price, the store sold 50 shirts in one week. Next week, the store declared a “sale – buy one get one free”. As a result, sale of the dress shirt increased to 300 in that week. Based on these information, calculate the price elasticity of demand using the arc elasticity formula (p 70-71 of the textbook). What does the coefficient of elasticity indicate? 2. Describe the relationship between price elasticity of demand and total revenue. As a manager, how will you decide what products to put on sale? Explain with appropriate examples. 3.
