Population of Fish in a Lake A lake is stocked with 100fish. Let f(1) be the number of fish after i months, andsuppose that y = f(1) satisfies the differential equationy' = .0004y(1000 – y). Figure 7 shows the graph of the solu-tion to this differential equation. The graph is asymptotic tothe line y = 1000, the maximum number of fish that the lakecan support.

Our model is good and probably explains a lot of variation. • B This is a bad sign for our model because a DGP of 0 means there is no relationship between the explanatory and outcome variable. • C This does not mean anything for our model.

Now assume we can derive an economic analysis from the biological relationship. Fisherman select the number of boats to operate - boats will be the choice of EFFORT. Boats Total Harvest 0 (tons) 0 100 200 300 400 500 600 700 800 900 1,200 2,200 2,800 3,000 2,800 2,400 1,600 800 Suppose the price of fish is $1,000 per ton. Suppose the cost to operate a boat for a year is $4,000. Construct a graph showing the total revenue and cost of the fishery. 0 What is the highest profit that can be earned, and how many boats are used for this? ( What is the corresponding long-run stock level associated with the profit-maximizing choice of effort? What is the profit earned if fisherman harvested the MSY? What number of boats are used in open access?

The revenue from the sale of a product is, in dollars, R = 1500x + 3000(2x+3)-1 - 1000 where x is the number of units sold. Find the marginal revenue when 200 units are sold. (Round your answer to two decimal places.) $ Interpret your result. If the sales go from 200 units sold to units sold, the revenue will increase by about $ Suppose that the weekly sales volume y (in thousands of units sold) depends on the price per unit (in dollars) of the product according to the following formula. y = 30(3p+ 1) −2/5, p > 0 (a) What is the rate of change in sales volume when the price is $24? (Round your answer to three decimal places.) dy = dp (b) Interpret your answer to part (a). (Round your answer to the nearest whole number.) If the price increases $1, the sales volume will decrease by If the demand for q units of a product priced at $p per unit is described by the equation p = 500 √29 + 7 find the rate of change of p with respect to q. dp = dq 1 units.

Salop circle spatial model Imagine a circular city with a circumference of 50 miles. A total of 500 people live around the city, all of whom are evenly spaced. It costs any person 10 cents per mile to travel. Every one of these people needs to have exactly one meal prepared. The cost of preparing meals is given by C(g) = 10 + 0.5q where q is the number of meals prepared at any restaurant. (Hint: Define one unit of distance as 50 miles if that makes the problem easier.) a.If you were interested in the efficient way to feed the population, how many restaurants would you build? Show work and explain b.If the market determines the number ofrestaurants, and the result is firms that make zero economic profit, how many firms will there be? Show work and explain C.

In a certain store, cashiers can serve 45 customers per hour on average. If a customers arrive at the store in a given hour, then the average number of customers C waiting in line can be modeled by the function x² C(x) = 2025 - 45x where x < 45. Answer the following questions with a graphing calculator. Round your answers to integers. 1) If 40 customers arrived in the store in the past hour, there are approximately 7 2) If there are 2 customers waiting in line, approximately customers waiting in line. customers arrived in the past hour.
