A country needs to build new power plants to meet the increasing demand for electric power. One possibility is to build coal-fired power plants, which cost $1300 per kW to construct and have an efficiency of 38 percent. Another possibility is to build clean-burning Integrated Gasification Combined Cycle (IGCC) plants where the coal is subjected to heat and pressure to gasify it while removing sulfur and particulate matter from it. The gaseous coal is then burned in a gas turbine, and part of the waste heat from the exhaust gases is recovered to generate steam for the steam turbine. The construction of IGCC plants costs about $1500 per kW, but their efficiency is about 48 percent. The average heating value of the coal is about 28,000,000 kJ per ton (that is, 28,000,000 kJ of heat is released when 1 ton of coal is burned). If the IGCC plant is to recover its cost difference from fuel savings in five years, determine what the price of coal should be in $ per ton. Consider the power generation capacity to be 150,000 MW

Answers

Answer 1

The price of coal is 64.69 $ per ton.

From the question, the differences in their masses can be seen when you find the total energy spent, their given efficiencies, and their heating value, as described in the equation below:

  m =mcoal - mIGGC

Note that, the total amount of energy (Etot) equals the given simple payback period (E. SPP)            

= Etot ÷ qHV ((1÷ηcoal) - (1÷ηIGCC))

= E. SPP ÷ qHV ((1÷ηcoal) - (1÷ηIGCC))

The amount of money saved using the IGCC is:

ΔM = (MIGCC - Mcoal) E

So to determine what the unit price of coal should be, we must consider the money saved, and the mass difference

Munit = ΔM ÷ Δm

(MIGCC - Mcoal) E  ÷ ((E. SPP ÷ qHV) (1÷ηcoal) - (1÷ηIGCC))

= qHV (MIGCC - Mcoal) ÷ spp ((1÷ηcoal) - (1÷ηIGCC))

The price of coal in $ per ton should be:

= 28 Х 10^6 (1500 - 1300) ÷ ( 5(1 ÷ 0.38) - (1 ÷ 0.48) x (365 x 24 x 60 x 60))

  = 28,000 000 X 200 ÷ (5( 2.632 - 2.083) (31,536 000))

= 64.69 $ per ton

In a summary, the answer is 64.69 $ per ton.

Explain how the Halloween holiday is related to economics.

Answers

Some argue that Halloween spending diverts resources that would be better spent on longer-term, more productive economic activity. While others argue that Halloween spending is inefficient at satisfying consumer wants, thus spurring more spending overall, causing the economy to grow. Example: the state of the economy affects the Halloween industry more than Halloween affects the state of the economy. In a down economy, for instance, consumers may be less likely to spend on frivolous goods such as costumes, candy, pumpkins, and home decorations. Or Conversely, booming economic times might serve as a boon to Halloween expenditures. Regardless of which way the relationship goes, many economists believe the increase in spending has a positive effect on the economy.

Donald is a minor. He can enter into any contract an adult can, provided a. Donald is willing to disaffirm the contract. b. the adult is willing to enter into contracts with minors. c. the contract is not one prohibited by law for minors. d. an adult is willing to ratify the contract.

Answers

Donald will be able to get into a contract with an adult if c. the contract is not one prohibited by law for minors.

Generally speaking:

the law does not allow minors to get into contracts with adults.There are times however, when a minor and an adult can enter into a form of contract.

For a minor and an adult to get into a contract, that particular type of contract must be allowed by law for minors and adults to be parties. If this is not the case, that contract is void.

In conclusion, Donald can enter into a contract that the law allows him to enter into with an adult.

Price is: always expressed in the United States in dollars and cents based on the expected value you will receive from your purchase based on the actual perception you will receive from your product also called revenue accurately described by none of the above

Answers

Considering the general market situation, Price is "always expressed in the United States in dollars and cents."

This can be proven by trying to make a purchase anywhere in the country.

The price of products is listed in dollars and cents. As such, the buyers would know the price of a product before making a purchase.

The other options are wrong because the price is not based on the expected value to receive and not on the actual perception.

Instead, Price is what the sellers feel is suitable for him, and it is expressed in dollars and cents.

Hence, in this case, the correct answer is option A. "always expressed in the United States in dollars and cents."

Colbert Inc. acquired 100% of Stewart Manufacturing on January 2, 2020. During 2020, Colbert sold Stewart $640,000 of goods, which had cost $450,000. Stewart still owned 18% of the goods at the end of the year. In 2021, Colbert sold goods with a cost of $820,000 to Stewart for $1,000,000, and Stewart still owned 15% of the goods at year-end. For 2021, the cost of goods sold totaled $5,800,000 for Colbert, and $1,300,000 for Stewart. What was consolidated cost of goods sold for 2021

Answers

Based on the information given the consolidated cost of goods sold for 2021 is $6,092,800.

First step is to calculate 2021 Intra-Entity Gross Profit

2021 Intra-Entity Gross Profit= ($1,000,000 − $820,000) ×15%

2021 Intra-Entity Gross Profit= $180,000 ×  15%

2021 Intra-Entity Gross Profit= $27,000

Second step is to calculate 2020 Intra-Entity Gross Profit

2020 Intra-Entity Gross Profit= ($640,000 − $450,000) ×18%

2020 Intra-Entity Gross Profit=$190,000 ×18%

2020 Intra-Entity Gross Profit = $34,200

Third step is to calculate consolidated cost of goods sold for 2021 using this formula

Consolidated COGS = Parent's COGS  + Subsidiary's COGS− Total COGS in Intra-Entity Transfer − Intra-Entity Gross Profit Deferred from 2020 + Intra-Entity Gross Profit Deferred from 2021

Let plug in the formula

Consolidated COGS =$5,800,000+ $1,300,000- $1,000,000-$34,200 +$27,000

Consolidated COGS = $6,092,800

Inconclusion the consolidated cost of goods sold for 2021 is $6,092,800.
