MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Assume that the demand function for tuna in a small coastal town is given by 28,000 91.5 (200 S 9 5 800) where p is the price (in dollars) per pound of tuna, and is the number of pounds of tuna that can be sold at the price p in one month. (a) Calculate the price (in $ per lb) that the town's fishery should charge for tuna in order to produce a demand of 400 pounds of tuna per month. $ per lb (b) Calculate the monthly revenue R (in dollars) op a function of the number of pounds of tuna q. R(q) = (c) Calculate the revenue and marginal revenue (derivative of the revenue with respect to a) at a demand level of 400 pounds per month. revenue marginal revenue per lb of tuna $ $ Interpret the results. At a demand level of 400 pounds per month, the revenue is and decreasing at a rate of $ per additional pound of tuna. (d) If the town fishery's monthly tuna catch amounted to 400 pounds of tuna, and the price is at the level in part (a), would you recommend that the fishery raise or lower the price of tuna to increase its revenue? O raise the price O lower the price Need Help? Rendit Watch it
