- Suppose the demand function for a product is given by the function: D(q) = -0.018q+50.4 Find the Consumer's Surplus corresponding to q = 1,550 units. (Do no rounding of results until the very end of your calculations. At that point, round to the nearest tenth, if necessary. It may help you to sketch the demand curve, which crosses the horizontal at q = 2,800.) dollars Answer:arrow_forwardSuppose that the price per unit p as a function of the demanda is p = 478.8 -0.9x. (a) Calculate the price elasticity of demand when x = 132. n = -2.44, therefore the demand is elastic (b) Calculate the price elasticity of demand when x = 425. n = -0.202 therefore the demand is inelastic (c) Find the demand that gives unit elasticity. x = 266.0 ✓arrow_forwardA microchip company is looking at new product lines and is reviewing the findings of its marketing team. The second product, a semiconductor microchip, has the elasticity of demand function: E(p)=√p^2-6p+5. If they set the price at $5.35 will the demand be elastic or inelastic? To increase the revenue should they raise the price or lower it?arrow_forward
- Consider the following demand function: 500 p(q) : (q + 290)? (a) Find the point elasticity n(g) as a function of q. The point elasticity function n(q): (b) Find the point elasticity at q = 520. Note: Point elasticity is typically a negative quantity. (c) Determine whether the demand is elastic, or inelastic, or has unit elasticity at q = 520. The demand is ? at q = 520.arrow_forwardThe demand function for a certain make of ink-jet cartridge is the following where p is the unit price in dollars and x is the quantity demanded each week, measured in units of a thousand. p= -0.02x² -0.2x+6 Compute the elasticity of demand when x = 11. (Round your answer to two decimal places.) 0.22 Determine whether the demand is inelastic, unitary, or elastic when x = 11. elastic inelastic O unitaryarrow_forward10arrow_forward
- What would the elasticity be if the demand function were Q = 150 -2P (USE P = 100)?arrow_forwardSuppose the demand for a product is given by D(p)=-8p+227. A) Calculate the elasticity of demand at a price of $18. Elasticity = (Round to three decimal places.) B) At what price do you have unit elasticity? (Round your answer to the nearest penny.) Price = $arrow_forwardThe weekly demand function is given by p+x+4xp = 68, where x is the number of thousands of units demanded weekly and p is in dollars. If the price pis decreasing at a rate of 91 cents per week when the level of demand is 5000 units, which one of the following statements is true? Demand is decreasing at 1330 units per week Demand is decreasing at 1470 units per week Demand is increasing at 1470 units per week O Demand is increasing at 1400 units per week O Demand is decreasing at 1400 units per weekarrow_forward
- The demand for ceiling fans can be modeled as D(p) = 25.02(0.992) thousand ceiling fans where p is the price (in dollars) of a ceiling fan. (a) Locate the point of unit elasticity. (Round your answers to two decimal places.) The point of elasticity occurs when p = $ and D(p) = thousand ceiling fans. (b) For what prices is demand elastic? For what prices is demand inelastic? (Round your numerical answers to two decimal places.) Demand is inelastic for < p < Demand is elastic for p ? ✓arrow_forward4x+200 A garden shop determines the demand function q = D(x) = 30x+9 during early summer for tomato plants where q is the number of plants sold per day when the price is x dollars per plant. (a) Find the elasticity. (b) Find the elasticity when x = 2. (c) At $2 per plant, will a small increase in price cause the total revenue to increase or decrease?
