A coal-fired power plant can produce electricity at a variable cost of $0.07 per kilowatt-hour when running at its full capacity of 30 megawatts per hour, $0.16 per kilowatt-hour when running at 20 megawatts per hour, and $0.24 per kilowatt-hour when running at 10 megawatts per hour. A gas-fired power plant can produce electricity at a variable cost of $0.12 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 $70 million, but it costs only $14 million to build a gas-fired plant.

Required:
a. Consider a city that has a peak afternoon demand of 80 megawatts of electricity. If it wants all plants to operate at full capacity, what combination of coal-fired plants and gas-fired plants would minimize construction costs?
b. How much will the city spend on building that combination of plants?
c. What will the average cost per kilowatt-hour be if you average over all 80 megawatts that are produced by that combination of plants?

Answer:

a-The construction of 2 coal-fired plants and 4 gas-fired plants will have minimum construction costs.

b-Total construction cost is $196 Million.

c-The average cost is $0.0825 per killowatt-hour.

Explanation:

a

In order to estimate the best combination of the two, consider the following linear programming model

[tex]30X+5Y\leq80\\X\geq0\\Y\geq0[/tex]

with minimizing function as [tex]70X+14Y[/tex]

This yeilds in the optimum solution of 2 coal fired plants and 4 gas fired plants with minimum construction costs.

The construction of 2 coal-fired plants and 4 gas-fired plants will have minimum construction costs.

b

The construction cost is as follows

Number of coal-fired plants=2

Number of gas-fired plants=4

Total Cost=(Cost of 1 Coal-Fired Plant*Number of coal-fired plants)+(Cost of 1 Gas-Fired Plant*Number of gas-fired plants)

[tex]\text{Total Cost}=(70\times 2)+(14\times4)\\\text{Total Cost}=140+56\\\text{Total Cost}=\$196 \text{Million}[/tex]

Total construction cost is $196 Million.

c

Average Cost of Electrici[tex]\text{Average Cost}=\text{Fraction of Coal-Fired}\times\text{Cost of Coal-Fired}+\text{Fraction of Gas-Fired}\times\text{Cost of Gas-Fired}\\\text{Average Cost}=\text{0.75}\times\text{0.07}+\text{0.25}\times\text{0.12}\\\text{Average Cost}=\$0.0525+\$0.03\\\text{Average Cost}=\$0.0825[/tex]ty production is given by estimating the share of electricity produced by coal-fired plants and gas-fired plants

Total energy=80 MW

Energy produced by Coal-Fired Plants at full capacity=2*30=60 MW

Energy produced by Gas-Fired Plants at full capacity=4*5=20 MW

Fraction of Coal-Fired Plants is given as

                                  [tex]\dfrac{\text{Coal-Fired Share}}{\text{Total Energy}}=\dfrac{60}{80}=0.75[/tex]

Fraction of Gas-Fired Plants is given as

[tex]\dfrac{\text{Gas-Fired Share}}{\text{Total Energy}}=\dfrac{20}{80}=0.25[/tex]

Cost of Producing KW-hr by Coal-Fired Plant is $0.07

Cost of Producing KW-hr by Gas-Fired Plant is $0.12

So

[tex]\text{Average Cost}=[\text{Fraction}_{Coal-Fired}\times\text{Cost per KW-hr}_{Coal-Fired}]+[\text{Fraction}_{Gas-Fired}\times\text{Cost per KW-hr}_{Gas-Fired}]\\\text{Average Cost}=(0.75\times0.07)+(0.25\times0.12)\\\text{Average Cost}=(0.0525)+(0.03)\\\text{Average Cost}=\$0.0825[/tex]The average cost is $0.0825 per killowatt-hour.

Hubert lives in San Diego and runs a business that sells boats. In an average year, he receives $851,000 from selling boats. Of this sales revenue, he must pay the manufacturer a wholesale cost of $476,000; he also pays wages and utility bills totaling $281,000. He owns his showroom; if he chooses to rent it out, he will receive $71,000 in rent per year. Assume that the value of this showroom does not depreciate over the year. Also, if Hubert does not operate this boat business, he can work as an accountant, receive an annual salary of $34,000 with no additional monetary costs, and rent out his showroom at the $71,000 per year rate. No other costs are incurred in running this boat business.

How to account for this $45,000? I think, this could be as Salary or dividend.
When Scott and Allison are in the store, they are the only ones who operate the register. Scott admits that, because he is in too much of a hurry, he sometimes puts the cash in his pocket rather than take the time to ring up the sale. Having cash in hand allows him to pay his babysitter and other personal expenses. Though it was difficult for him to be certain, Scott estimated that transactions worth about $45,000 each year have been handled in this way. Scott confirmed that he has not filed a personal tax return since he started GPP because he has not taken a salary.
