charlie’s utility function is u(xa, xb) = xaxb. his income is $80. if the price of xa is $4 and the price of xb is $5, how many units of good xa will charlie demand?

Answers

Answer 1

Charlie’s utility function is u(xa, xb) = xaxb. his income is $80. if the price of xa is $4 and the price of xb is $5

Charlie will demand 10 units of good xa.

Charlie's utility function is u(xa, xb) = xaxb, which means that his utility is derived from the quantities of two goods, xa and xb, that he consumes.Given that his income is $80, and the price of xa and xb are $4 and $5, respectively, we can use the concept of marginal utility to determine how much of good xa he will demand.


Marginal utility refers to the additional utility derived from consuming an extra unit of a good. In this case, the marginal utility of good xa is given by the partial derivative of Charlie's utility function with respect to xa, holding xb constant:


MUxa = ∂u/∂xa = xb


This means that for every additional unit of good xa that Charlie consumes, he gains an additional xb units of utility. To maximize his utility, Charlie should allocate his income in such a way that the marginal utility per dollar spent is equal for both goods. This is known as the principle of equal marginal utility.


Using the prices of the two goods, we can calculate the marginal utility per dollar spent on each good:

MUxa/Pxa = xb/4
MUxb/Pxb = xa/5

Setting these two expressions equal to each other, we get:

xb/4 = xa/5

Solving for xa, we get:

xa = (5/4)xb

Since we know that Charlie's income is $80, we can plug in the prices and solve for the quantity of xa that he will demand:

80 = 4xa + 5xb
80 = 4(5/4)xb + 5xb
80 = 10xb
xb = 8

Substituting back into our equation for xa, we get:

xa = (5/4)xb = 10

Therefore, Charlie will demand 10 units of good xa.

Which of these are true of a natural pause following a conversation?
You should begin speaking to avoid awkwardness.
You should not panic.
Take a moment to collect your thoughts before you speak.
Conversations that end with a pause went poorly.

Answers

Answer: all of the above.

Why? Because all of them are important in a conversation!
speaking to avoid awkwardness is good so you won’t end up ruining the conversation without realizing and giving the other person a bad impression about yourself. And not panicking is quite important too, because when you panic and get negative thoughts you’ll realize that it’s keeping you down and making you feel bad or anxious about every single word you say. And lastly collecting your thoughts and putting them in order (few seconds before starting a conversation) can be helpful to most people which will make them feel more confident and prepare especially if the conversation was serious.

You should not panic

Answers

Answer:

Comedy as a Profession is a great example.

Explanation:

The science of it is related to the psychology of what makes people laugh.

If studied, one would realize that there are certain things that are bound to make people laugh (all things being equal). An example is when a person makes fun of themself to an audience.

To explain this, scientists have stated that it is inherent in humans to laugh at the misfortune of others. However, this is just a theory and does not explain why we laugh at other kinds of comedy.

A plausible explanation (which is more recent in the parlance of psychology) is that people also laugh when certain expectations are defied in a very witty manner.

As a professional stand-up comedian, knowing all the rules and tricks is just one part of the coin. Being able to, either by practice or repeated efforts during practice, internalize these principles, practice them and effectively use them is the artistic part of the picture.

There those who are gifted naturally with a principle thought process that elicits laughter from others, would be termed hilarious. However, to make a living out of comedy, one would need to fully understand the principles and practice to deliver them as naturally as possible.

Another paradigm to the art of comedy is that, it has to be very witty. Wit many times may come with an element of suprise... a new angle that was previously "unthought" of.

On January 1, Salter Corporation determined that its direct materials inventory needs to contain 6,000 pounds of materials by March 31. To achieve this goal, Salter will have to use four pounds of direct materials for every pound that it purchases during the upcoming quarter. On the basis of the company's budgeted sales volume, management estimates that 5,000 pounds of direct materials need to be purchased by March 31. Determine the number of pounds in Salter's beginning direct materials inventory on January 1.

Answers

Answer: 21000

Explanation:

Direct materials inventory desired = 6,000

Purchase of direct materials budgeted = 5000

Pounds needed for production = 5000 × 4 = 20000

The number of pounds in Salter's beginning direct materials inventory on January 1 will be:

= Direct materials inventory desired + Pounds needed for production -

Purchase of direct materials budgeted

= 6000 + 20000 - 5000

= 21000 pounds
