Answer:

In order to meet the needs of its people, every society must answer three basic economic questions:

What should we produce?

How should we produce it?

For whom should we produce it?

Every society, regardless of its political structure, must develop an economic system to determine how to use its limited productive resources to answer the three basic economic questions of what, how, and for whom to produce.

Answer:

When there is inflation, there is a large amount of money in circulation, which causes it to lose value and, therefore, a greater amount of money is required to acquire a certain good. Therefore, to curb inflation, it is necessary to decrease the money supply in circulation, that is, withdraw dollars from society and place them in the financial and banking system, to curb consumption and encourage investment.

Therefore, the Federal Reserve must carry out actions aimed at removing this money from circulation, which it can carry out through two fundamental actions: on the one hand, by raising the reserve requirements of banks, with which they can lend less money, thus slowing down monetary circulation; and on the other, raising the interest rate on debt bonds, thus promoting the outflow of money from consumers to the financial market.

Answer:

i. 240 tickets

ii. 80 adults and 160 children

iii. N$ 40,000.00

iv. Profit= N$ 36,800.00

Explanation:

Ok so in order to solve this problem we need to start by building our system of equations from the restrictions the problem gives us:

let's say that

x=# of adult tickets

y= # of children tickets

so

"... the concert venue can accommodate at most 240 people."

this translates to the following inequality:

[tex]x+y\leq240[/tex]

"The organizeres are giving a N$20 discount to every adult and N$10 discount for every child but do not want the total descounted amount to exceed N$3200."

Translates to

[tex]20x+10y\leq3200[/tex]

and we know we cannot sell a negative number of adult and children tickets so the last restrictions are:

[tex]x\geq0[/tex]

[tex]y\geq0[/tex]

so we can now graph our system of inequalities (see graph attached)

the procedure to graph a linear equation is as follows:

1. Pick an x-value

2. Find the corresponding y-value with the provided equation we need to graph.

3. Write the coordinates as an ordered pair (x,y)

4. Repeat the process with a second x-value.

5. Graph the two points you found on the previous steps.

6. Connect the points with a straight line.

So the feasible region is the one that all restrictions will have in common and the maximum and minimum points for our objective function will be the marked points, which are the vertices of the feasible region. So we test them to see which will maximize our objective function.

Objective function:

s=200x+150y

(0,0)

s=200(0)+150(0)=0

(0,240)

s=200(0)+150(240)=N$36,000

(80,160)

s=200(80)+150(160)=N$40,000

(160,0)

s=200(160)+150(0)=N$32,000

So when comparing the results we can see that the objective function will be maximized at the point (80,160) so:

i) How many tickets altogether should the organisers sell in order to maximize their sales amount?

total # of tickets = x+y = 80+160=240 tickets

ii) How many tickets of each type (adult and child) should they sell to get a maximum sales amount?

x                                   y

80 adult tickets and 160 child tickets.

iii) What is the maximum sales amount the organizers can make?

s=200(80)+150(160)=N$40,000

iv) If the profit is calculated as follows: profit = total sales - total discount amount. How much profit will the organisers make from the maximum sales?

Profit= total sales - total discount

total sales=200(80)+150(160)=N$40,000

total discount = 20(80)+10(160)=N$3,200

Profit=N$40,000-N$3,200=N$36,800.00

Answer:

To tune a piano, you would start by playing the piano's "A" key while ringing an "A" tuning fork.

If the piano is out of tune, you'll hear a distinct warble between the note you're playing and the note played by the tuning fork; the further apart the warbles, the more out-of-tune the piano. By either tightening or loosening the piano's strings, you reduce the warble until it's in line with the tuning fork. Once the "A" key is in tune, you would then adjust all of the instrument's 87 other keys to match.

Explanation:

Most tuning forks are made to vibrate at 440 Hz, a tone known to musicians as "concert A."

In this question there are some errors; here is the complete and correct question

Bartering involves exchanging goods and services. But today, _________can be exchanged for goods and services. A)money B)cost C) price

The correct answer is But today, money can be exchanged for goods and services

Explanation:

Bartering was a basic economic system in which individuals exchanged one product or service for another. For example, you can exchange a pound of rice for one of fruit. This was used in early communities before money was invented; however, nowadays bartering is not common in modern societies. This is because there is money or representations of it such as checks, credit cards, etc. and this is used to get goods and services. This means, today, it is money rather than other products the item use to obtain goods and services.

This is true.
