AMC Theaters is considering raising the price of its tickets from $10 to $13. In order to make sure that this strategy is profitable, the theater is testing a pricing increase of $1.00 throughout America. For each $1.00 increase, demand drops 5%; demand is 3500 units when the tickets are priced at $10. The theater's fixed costs are $10,000 and unit variable cost is $3. Based on this information, calculate the following: a. The price elasticity of demand. Is it elastic, inelastic, or unitary elastic? b.Calculate the demand, fixed costs, variable costs, and profit for each price (i.e = $10, $11, $12, $13). What is the most profitable selling price and what profit should the theater expect at this price?
The total cost a power plant ($/megawatts) to produce electricity is Y=12+1.3X+0.24 X2 , where X is in megawatts. The estimated selling price of electricity is (16-0.23X) per megawatts. Find the value of X that maximizes profit. Group of answer choices Less than 10 megawatts Between 10-12 megawatts Between 12-14 megawatts More than 14 megawatts Dont
2. (This problem derives the general result that any polynomial function is of a lower asymptotic order than any exponential function.) First, we prove a special case. Suppose that we have two functions, f(n) = n² and g(n) = 2". We will prove that f(n) = O(g(n)). • port (a). (c) Show that, for any n ≥ no, it must be the case that f(n) ≤ cog(n) = f(n+1) ≤ cog(n+1). Precisely state the argument by induction that n² = 0(2¹). Now, define f(n) = nk where k ≥ 1, g(n) = a", where a ≥ 1. (d) (Slightly harder). Argue that, for any k and a, there exists some n₁ such that : (1₁+¹)* < a.

(f) (Harder) Show that, for any n ≥ n₁, it must be the case that f(n) ≤ cig(n) ⇒ f(n+1) ≤ cig(n+1), and therefore nk = O(a") for all k, a ≥ 1.
You manufacture ceramic lawn ornaments. After several months your accountant tells you that your profit P(n) can be modeled by the function P(n)= -0.002n^2+5.2n-1208 where n is number of ornaments sold each month. A) How many ornaments must you make and sell to break even. B) How many ornaments must you make and sell to maximize profit. C) What is the maximum profit. D) How many ornaments must you make and sell in order to earn a profit of $1657.

(d) How big must AL be in order for the difference between Q(100000, 243+AL) and its linear approximation Q(100000, 245) + -DAL, to differ by more than two units?
Assume that it costs a company approximately C(x) = 400,000 + 180x + 0.001x² dollars to manufacture x smartphones in an hour. (a) Find the marginal cost function. Use it to estimate how fast the cost is increasing when x = 10,000. $ per smartphone Compare this with the exact cost of producing the 10,001st smartphone. The cost is increasing at a rate of $ per smartphone. The exact cost of producing the 10,001st smartphone is $ Thus, there is a difference of $ (b) Find the average cost function C and the average cost to produce the first 10,000 smartphones. C(x) C(10,000) $ (c) Using your answers to parts (a) and (b), determine whether the average cost is rising or falling at a production level of 10,000 smartphones. The marginal cost from (a) is ---Select--- O than the average cost from (b). This means that the average cost is ---Select--- O at a production level of 10,000 smartphones.
A large company in the communication and publishing industry has quantified the relationship between the price of one of its products and the demand for this product as Price=160−0.02×Demand for an annual printing of this particular product. The fixed costs per year (i.e., per printing)=$47,000 and the variable cost per unit=$40. What is the maximum profit that can be achieved? What is the unit price at this point of optimal demand? Demand is not expected to be more than 4,000 units per year. The maximum profit that can be achieved is $? (Round to the nearest dollar.) The unit price at the point of optimal demand is $? per unit.
