A manufacturer of DVD players has weekly fixed costs of $1,540 and variable costs of$11.50 per unit for one particular model. The company sells this model to dealers for $18.50 each. (a) For this model DVD player, write the function for weekly total costs C(x). C(x) = (b) Write the function for total revenue R(x). R(x) = (c) Write the function for profit P(x). P(x) = (d) Find C(150). C(150) = Interpret C(150). For each$1 increase in cost this many more DVD players can be produced. When this many DVD players are produced the cost is $150. For every additional DVD player produced the cost increases by this much. This is the cost (in dollars) of producing 150 DVD players. Find R(150). R(150) = Interpret R(150). For every additional DVD player produced the revenue generated increases by this much. When this many DVD players are produced the revenue generated is$150. For each $1 increase in revenue this many more DVD players can be produced. This is the revenue (in dollars) generated from the sale of 150 DVD players. Find P(150). P(150) = Interpret P(150). For each additional DVD player sold the profit (in dollars) increases by this much, but since it is negative it means that the company needs to decrease the number of DVD players sold in order to make a profit. This is the profit (in dollars) when 150 DVD players are sold, but since it is negative it means that the company loses money when 150 DVD players are sold. For each additional DVD player sold the profit (in dollars) increases by this much, but since it is positive it means that the company is producing too many DVD players. This is the profit (in dollars) when 150 DVD players are sold, and since it is positive it means that the company makes money when 150 DVD players are sold. (e) Find C(400). C(400) = Interpret C(400). For each$1 increase in cost this many more DVD players can be produced. For every additional DVD player produced the cost increases by this much. This is the cost (in dollars) of producing 400 DVD players. When this many DVD players are produced the cost is $400. Find R(400). R(400) = Interpret R(400). This is the revenue (in dollars) generated from the sale of 400 DVD players. For every additional DVD player produced the revenue generated increases by this much. For each$1 increase in revenue this many more DVD players can be produced. When this many DVD players are produced the revenue generated is $400. Find P(400). P(400) = Interpret P(400). For each additional DVD player sold the profit (in dollars) increases by this much, but since it is negative it means that the company needs to decrease the number of DVD players sold in order to make a profit. This is the profit (in dollars) when 400 DVD players are sold, but since it is negative it means that the company loses money when 400 DVD players are sold. For each additional DVD player sold the profit (in dollars) increases by this much, but since it is positive it means that the company is producing too many DVD players. This is the profit (in dollars) when 400 DVD players are sold, and since it is positive it means that the company makes money when 300 DVD players are sold. (f) Find the marginal profit MP. MP = Write a sentence that explains its meaning. Each additional DVD player sold increases the profit by this many dollars. When costs are decreased by this much the profit is increased by$1. For each $1 increase in profit this many more DVD players can be produced. When revenue is increased by this much the profit is increased by$1.

The correct answers are Black Markets, Underground and Higher.

Explanation:

Black markets are illegal markets that emerge in response to price controls. A few buyers are able to obtain the good at the open-market price; the rest must resort to illegal means. The additional demand is met by underground suppliers selling at much higher prices.

Government of a country does not support or encourage such activities. People usually buy such products at market rate when the product is low in demand and sell it in black at higher prices when the demand of the product is high.

Explanation:

The connotative meaning is a word's implied or secondary meaning, in addition to its literal meaning.

Connotative meaning gives an idea or a feel that invokes for a person other than literal context of the word.

Connotation tells us weather the word used is in positive context or the negative one. For example, the words childish and youthful have same denotations but connotative meaning of childish is negative while youthful lies in positive context.

I’m assuming this question is in reference to a text book... In case you didn’t know, a glossary is a list of words and their definitions, usually at the end of a book or chapter. What the question is asking for is where else in the book can you find a list of words + their definitions related to Geography. To get started, you might want to check the end of each chapter.

Hope I helped (:

The government does not support the black market or any of their actions with getting items and selling them in other forms. Those who are in demand of a good when they have a hard time in getting it may purchase it illegally at a higher price just so they can receive that good. When there is an exchange of goods in the black market, these items are usually prohibited by the government and therefor illegally being sold.

TRUE

Explanation:

Because the price is below equilibrium the quantity will fall and shortage will ocour. Because of that the price in the black market will become even higher than it was before the price control, making the price control counter productive.

So this additional demand is met at much higher prices than legal market.

The answer is (F).  The word​ "per" means divided by because it implies division.

Step-by-step explanation:  We are given six options out of which we are to select the correct one that explains the meaning of word 'per'.

Suppose we are talking about speed of a car as "k miles per minute".

It means that the car travels k miles in 1 minute. That is

$\textup{k miles per minute}=\dfrac{\textup{k miles}}{\textup{1 minute}}.$

If the car travels 25 miles in 5 minutes, then its speed will be

$S=\dfrac{25~\textup{miles}}{5~\textup{minutes}}=5~\textup{miles per minute}.$

Therefore, the word 'per' simply means division.

Thus, the correct option is (F).
