Answer:

C(t)=0.1t+25

Explanation:

So, we are looking for a linear equation. As we know Equation of a line has different forms, let´s use slope-intercept form:

C(t)=mt+b

Where C is the total cost as a function of t, t is the amount of airtime in minutes, m is the slope and b is the y-intercept

Now, let´s use the data provide in order to find m and b:

40=150m+b   (E1)

55=300m+b   (E2)

We have a 2X2 system of equations, let´s solve it using elimination method:

2(E1)-(E2)

25=0+b\\b=25

Replacing b in (E1) or (E2):

m=\frac{40-25}{150}

m=\frac{1}{10}=0.1

Knowing the slope m and the y-intercept b the linear model that represents the total cost as a function of t is:

C(t)=0.1t+25

You can check the results evaluating t=150 and t=300, the results must be 40 and 55 respectively

Here are the options to this question :

a. the person with the lowest wage rate.

b. the low opportunity cost producer.

c. the person with the most advanced technical knowledge.

d. the person that can accomplish the task most rapidly.

a country has comparative advantage in production if it produces at a lower opportunity cost when compared to other countries.

For example, country A produces 10kg of beans and 5kg of rice. Country B produces 5kg of beans and 10kg of rice.

for country A,

opportunity cost of producing beans = 5/10 = 0.5

opportunity cost of producing rice  = 10/5 = 2

for country B,

opportunity cost of producing rice = 5/10 = 0.5

opportunity cost of producing beans  = 10/5 = 2

Country A has a comparative advantage in the production of beans and country B has a comparative advantage in the production of rice

When a company is using the direct​ write-off method, and an account is written​ off, the journal entry consists of a​ ________.
MA_775_DIABLO [31]

Answer:

B.

Explanation:

An uncollectible account or bad debt is an account receivable that the business cannot collect. Businesses account for bad debts by using :

-the allowance method.

-the direct write-off method .

The direct write-off method is primarily used by businesses with few credit customers. When it is determined that a customer is not going to pay, the uncollectible account is removed from the records.

To remove from the records, there is a credit to Accounts Receivable (asset account, increase by the debit) and a debit to Bad Debts Expense (expense account, increase by the debit).
