Answers and explanations:

1) A modification problem takes places when creating a database two different type of information is entered in the same chart row generating inaccuracy. The only form to solve this issue is creating a new row so each piece of information will be stored in one row particularly.

2) There are three (3) types of modification problems: the deletion problem (the single row containing information from different themes can be deleted losing data), the update problem (new information entered could lead to more inconsistency), and the insertion problem (similar to deletion, a new row can be inserted instead of the row causing problem but information will be missing).

What will happen to the firms equilibrium wage rate when the supply of labour decrease from 25 to 15? Explain with the help of d

Tpy6a [65]

Answer:

Wage rate = $960

Explanation:

Supply of labor is the number of hours workers are willing to work at a given real wage rate. When wage rate increases, supply of labor also increases because more people are encouraged as now they can obtain a higher income. When wage rate decreases, labor supply also decreases.

In this case, however, there has been a decrease in supply, causing the supply curve to shift from S to S1. This can be due to many reasons such as migration, increase in minimum working age or increase in interest in education causing more people to study. When the supply of labor falls, there are less people available for work. Thus, demand exceeds supply, causing a shortage. Hence, the pressure causes price, i.e. wage rate to increase. To determine by how much the increase is, cross-multiplication can be used:

At 25 laborers, wage rate is $600 (25 = 600)

At 15 workers, wage rate is X (15 = X)

We now substitute for X, which is the amount by which wage rate will increase.

25 / 600 = 15 / X

Thus, 25X = 9000 (600 x 15)

9000 / 25 = X

X = 360.

Hence, wage rate at 15 laborers is 600 + 360 = $960

Expropriation is the seizure of private property by a government entity or government agency for the purpose of public interest. Usually owners that lose property due to expropriations, receive some type of compensation for their loss.

A common example of expropriation is land being taken away for building roads or dams.

Tasya [4]

Answer:

$67860

Explanation:

sell price of each toaster= $24.45

variable cost per unit= $16.65

total fixed cost= $25,700

number of unit sold x= 8700

the formula for contribution margin is

= sales price- variable cost

= (s-v)x

putting values we get

= $(24.45-16.65)\times8700$

= $67860

Hence the contribution margin the above case will be $67860

Why does a taxminusdeferred retirement account accumulate more money than a taxable account, assuming the same amount is contri

skad [1K]

Answer:

Simply because tax-deferred accounts are taxed only when the investor receives or withdraws money from them. For example, a 401 (K)'s interest and capital gains are not taxed until the beneficiary retires and starts to receive payments, and that may take a long time.

It is not the same to be taxed immediately, because that reduces the amount invested. For example, you invest have $100 to invest and your income tax rate is 22%.

a tax-deferred account that earns 5% per year will earn $5, and then the principal will increase to $105 for the next, and keep earning more money.
a taxable account will only have a $78 after taxes are paid, and if it earns 5%, then it will only earn $3.90 at the end of the year, and the principal will increase to $81.90.
