A coal-fired power plant can produce electricity at a variable cost of 4 cents per kilowatt hour when running at its full capacity of 30 megawatts per hour, 16 cents per kilowatt hour when running at 20 megawatts per hour, and 24 cents per kilowatt hour when running at 10 megawatts per hour. A gas-fired power plant can produce electricity at a variable cost of 12 cents per kilowatt-hour at any capacity from 1 megawatt per hour to its full capacity of 5 megawatts per hour. The cost of constructing a coal-fired plant is $50 million, but it costs only $10 million to build a gas-fired plant. a. Consider a city that has a peak afternoon

- A company manufactures two types of leaf blowers: an electric Turbo model and a gas-powered Tornado model. The company's production plan calls for the production of at least 690 blowers per month. It costs $74 to produce each Turbo model and $111 to manufacture each Tornado model, and the company has at most $63,640 per month to use for production. Find the number of units that should be produced to maximize profit for the company, and the maximum profit, if the profit on each Turbo model is $35 and the profit on each Tornado model is $40. The maximum value is $ by producing integers or decimals.) units of the Turbo model and units of the Tornado model.

- Tim lives in Vancouver and runs a business that sells pianos. In an average year, he receives $733,000 from selling pianos. Of this sales revenue, he must pay the manufacturer a wholesale cost of $433,000; he also pays wages and utility bills totalling $257,000. He owns his show room; if he chooses to rent it out, he will receive $13,000 in rent per year. Assume that the value of this show room does not depreciate over the year. Also, if Tim does not operate this piano business, he can work as a paralegal, receive an annual salary of $23,000 with no additional monetary costs, and rent out his show room at the $13,000 per year rate. No other costs are incurred in running this piano business.arrow_forwardKenji lives in Mississauga and runs a business that sells pianos. In an average year, he receives $723,000 from selling pianos.

- PROBLEM #3 An auto parts manufacturer uses a production process for one of its parts that has a long- run production function as follows: q=20K²L, where L measures the number of labor hours and K measures the number of rental hours for the machine used in the production process. The machine can be rented for $90 per hour; the hourly wage for workers is $15. The manufacturer has a production budget of $23,220 for this type of part. If the manufacturer's goal is to maximize output, subject to the production budget, find the output-maximizing levels of capital and labor the manufacturer will choose.arrow_forwardSuppose you own a small business. Last month, your total revenue was $8,800.
