- 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_forwardK A retail chain will buy 700 cordless phones if the price is $40 each and 500 if the price is $50. A wholesaler will supply 550 phones at $20 each and 1950 at $60 each. Assuming that the supply and demand functions are linear, find the market equilibrium point and explain what it means. Market equilibrium occurs when the number of units is and the price is $ per unit.arrow_forwardFind the demand functionarrow_forward
- What is the "quantity demanded"? A) the maximum amount of a good that can be consumed during a specific time period B) the amount of a good people are able and willing to buy during a specific time period and at a given price C) the amount of a good people desire D) the amount of a good people are able and willing to buy at all possible pricesarrow_forwardFor the following demand function: Q(P) = 2015 - 31P Calculate the price where the quantity demanded falls to zeroarrow_forwardConsider the horizontal sum of the two demand curves P = 8- Q and P = 12- Q.
