Use the function below (whose parameters qualify it as a STC function) to answer the questions. STC = 4850 + 40Q - 1.5Q^2 + .04Q^3 FC = $4,850 AFC = 4,850 / Q (I calculated this) AVC = 40 - 1.5Q + .04Q^2 (I calculated this) MC = 40 - 3Q + 0.12Q^2 (I calculated this)
CINESA, a government-owned power company that normally uses natural gas for electricity generation, is purchasing fuels other than natural gas and power from a commercially built wind farm, often at extra costs, which are transferred to the customer. Total monthly fuel and wind-power costs are now averaging $6,800,000. An engineer with the utility has calculated the average revenue for the past 24 months using three fuel-mix and wind-power situations: all gas, < 30% other or wind, and ≥ 30% other or wind. The table below shows the number of months for each situation and the associated revenue. If the same situation persists for the next 2 years, determine whether the utility’s revenue will be greater or less than the costs and by how much. Fuel/Wind Situation Months in Past 24 Average Revenue, $/Month All gas 12 $5,270,000 < 30% other/wind 9 $7,850,000 ≥ 30% other/wind 3 $12,130,000
An apple grower has discovered a process for producing oranges that requires two inputs. The production function is Q = min{2x, y}, where x and y are the amounts of inputs 1 and 2 that he uses. The prices of these two inputs are wx = $5 and wy = $10, respectively. The minimum cost of producing 160 units is therefore:a. $2,400.b. $1,600c. $800.d. $2,000.e. $8,000.

The profit,P,of a company that manufactures and sells N units of a certain product is modeled by the function P(N)=R(N)-C(N) The revenue function,R(N)=S·N, is the selling price S per unit times the number N of units sold. The company's cost,C(N)= Co +Cop(N), is a sum of two terms. The first is a constant Co describing the initial investment needed to set up production. The other term, Cop(N), varies depending on how many units the company produces, and represents the operating costs. Companies care not only about profit, but also marginal profit, the rate of change of profit with respect to N. Assume that S=$50,Co=$75,000, Cop(N)=$50✓N,and that the company currently sells N= 100 units. Compute the marginal profit at this rate of production.Round your answer to one decimal place.
A firm believes a product’s sales volume (S) depends on its unit selling price (P) as S = $100 − P. The production cost (C) is $1000 + 10S. (a) Graph the sales volume (S) from 0 to 100 on the x axis, total cost and total income from $0 to $2500 on the y axis, C = $1000 + 10S, and plot the curve of total income. Mark the breakeven points on the graph. (b) Determine the breakeven point (lowest sales volume at which total sales income just equals total production cost). (c) Determine the sales volume (S) at which the firm’s profit is a maximum.
A vacuum cleaner retailer has been selling 84 units per month of the basic Bissell stick model for $80. The retailer’s variable costs for that model are $51. (a) If a retail manager has only the information provided above, calculate the breakeven sales level for lowering the price of the basic Bissell stick model to $72. Show your work. (b) Assume that the retail manager then finds out that when a customer buys a Bissell stick model, the customer also spends an average of $20 for vacuum cleaner bags and that the retailer’s contribution margin on vacuum cleaner bags is 55%. Given this additional information, recalculate the breakeven sales level for lowering the price of the basic Bissell stick model to $72. Again, show your work. (c) Would having the additional information about the vacuum cleaner bags make it easier for the manager to make more profit from the price decrease or would it make it harder for her to do so? Explain your reasoning.
1. Prepare the scatter diagram and insert the trendline or line of best-fit. Use a scaleof 2 cm to represent 1,000 units on the x-axis & 2 cm to represent $50,000 on the y-axis. 2. Using the line of best-fit, determine the company’s fixed cost per month and thevariable cost per unit. (Use 0 & 5,000 units.)
A company has established that the relationship between the sales price for one of its products and the quantity sold per month is approximately D = 1560 – 20p units (D is the demand of quantity sold per month, and p is in dollars.) The fixed cost is $800 per month, and the variable cost is $30 per unit produced. The demand that maximizes the revenue is:
If a person performing a task has been achieving an 75 percent learning curve and if it took 53 minutes to produce the first unit, the total time to produce 800 units will be 4165.3 minutes. True False
How is MC calculated? 300 for the first MC is incorrect.
A company has determine the price and the monthly demand of its products are related by the equation D= √400-p where p is the price per unit in dollar and D is the monthly demand. The associated fixed costs are $1,125 per month and the variable costs are $100/unit. Use this information to answer the following: What is the optimal number of units that should be produced and sold each month? Determine the value of D that represents the break-even point?
