- Suppose that the demand for sweatshirts at the university bookstore is given by: P = 40 – 0.2Q A) Using the point elasticity method, price elasticity of demand at a price of $8 is B) Is the demand for sweatshirts elastic or inelastic at the price of $8?arrow_forwardThe demand for hair dryers is described by the following function: P= 240-5Qd If the price is $185, what is the quantity demanded? If the price is $185, what is the total revenue? If the price is $175, what is the quantity demanded? If the price is $175, what is total revenue? Compute the price elasticity of demand at the average price of $180.arrow_forwardWhat would the elasticity be if the demand function were Q = 150 -2P (USE P = 100)?arrow_forward
- Suppose the demand function for smart phones is given by Q(P) = AP¹-a 1-a where A> 0 and a > 1. Use calculus to show that the price elasticity is equal to 1 — a everywhere along the whole curve. (Hint: Recall that if f(x) = x³, then ƒ'(x) = ßxß-¹). Interpret this result.arrow_forwardABC Manufacturing has determined that the demand function for their heated socks is given by: 6 D(p) = 170 --p². a. Find E(p), the Elasticity of Demand as a function of price, p. E(p) = b. Find the Elasticity of Demand when heated socks are selling at a price of $5. Give result accurate to at least 3 decimal places. E(5) c. At this price ($5): We would say the demand for heated socks is: [Select an answer Based on this, in order to increase revenue we should: [Select an answer d. Use the Elasticity model to determine the price that maximizes revenue. (Round result to 2 decimal places.) P =arrow_forwardProblem Number 8 Economics: Elasticity of Demand for DVD Rentals. The demand for DVD rentals at Klix Video is given by q= D(x) = 120 - 20x, where q is the number of DVDs rented per day at x dollars per rental. Find each of the following. a) The elasticity as a function of x b) The elasticity at x = 2 and at x = c) The value of x for which E(x) = 1. Interpret the meaning of this price. d) The total-revenue function, R(x) = (x) D(x) e) The price x at which total revenue is a maximum 4. Interpret the meaning of these values of the elasticity.arrow_forward
