Light emitting diode (LEDs) light bulbs have become required in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent light bulb costs $.53 and lasts for 1,000 hours. A 15-watt LED, which provides the same light, costs $3.80 and lasts for 12,000 hours. A kilowatt hour of electricity costs $.129. A kilowatt-hour is 1,000 watts for 1 hour. However, electricity costs actually vary quite a bit depending on location and user type. An industrial user in West Virginia might pay $.04 per kilowatt-hour whereas a residential user in Hawaii might pay $.25. You require a return of 9 percent and use a light fixture 500 hours per year. What is the break-even cost per kilowatt-hour? (Do not round intermediate calculations and round your answer to 6 decimal places, e.g., 32.161616.) Break-even cost

Jenny Tanaka wants to buy a new car, and the annual gasoline expense is a major consideration. Her present car gets 25 miles per gallon (mpg), and she is considering purchasing a new car that gets 40 mpg. Jenny now drives about 12,000 miles per year and pays $3.25 per gallon of gasoline. She therefore calculates an annual gasoline consumption of 480 gallons for her 25 mpg car (12,000 miles/25 mpg) compared to 300 gallons consumed per year for the 40 mpg car (12,000 miles/40 mpg). Since driving the higher- mileage car would use 180 gallons less per year, Jenny estimates the new car will save her $585 in gasoline expense per year (180 gallons 3 $3.25 per gallon). Suppose Jenny buys the 40 mpg car. According to economic theory, Jenny's actual annual savings on gasoline will be 7 1 C 1 U C VI 10 V K W S TACAZEC 10 GUNS TOMBER 2 than her initial estimate of $585.
You are considering adding a new software title to those published by your highly successful software company. If you add the new product, it will use capacity on your disk duplicating machines that you had planned on using for your flagship product, "Battlin' Bobby." You had planned on using the unused capacity to start selling "BB" on the West coast in two years. You would eventually have had to purchase additional duplicating machines 10 years from today, but using the capacity for your new product will require moving this purchase up to 2 years from today. If the new machines will cost $115,000 and can be expensed under Section 179, your marginal tax rate is 21 percent, and your cost of capital is 16 percent, what is the opportunity cost associated with using the unused capacity for the new product? (Negative amount should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 2 decimal places.) Opportunity cost
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 Rosebud Motel is a must-stay for any road-tripper or weary traveler. The motel fils each of its 24 rooms for 200 nights each during the year. Annual fixed costs total $160,000. The variable cost of one night's stay is $100. The motel owners expect a 50% return on the company's $500,000 of assets each year. The Rosebud Motel is currently the only place to stay for 50 miles. What should Rosebud's cost-plus price be if sales volume and costs are expected to stay consistent? OA. $133.33 OB. $185.42 OC. $2,150.00 OD. $152.08 OE. The Rosebud Motel would not set its price as it is a price-taker in this market.
The total cost a power plant ($/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
Electricity is produced with water according to the function: E = 5 + 5W-1W² where E = kilowatt-hour and W = gallons of water. Water costs $0.02 per gallon. Electricity can be sold on the grid for $0.10 per kWh (kilowatt-hour). How much water should be purchased?

In a building construction project, 7,500 feet of insulated ductwork is required. The ductwork is made from 14-gauge steel costing $8.50 per pound. The 24-inch-diameter duct weighs 15 pounds per foot. Insulation for the ductwork costs $10 per foot. Engineering design will cost $16,000, and labor to install the ductwork will amount to $180,000.

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.
