Correct Answer: B. Code of Conduct Bureau

Explanation

ai.

C = 30 + 4q

when q = 18units

C = 30 + 4(18)

= 30 + 72

= 102 dollars

aii.

C = 30 + 4q

when q = 36 units

C = 30 + 4(36)

= 30 + 144

= 174 dollars

bi.

At 28 units

Average cost = \(\frac{Total Cost}{Quantity}\)

NOTE: TC = C = 30 + 4q

Therefore, AC =\(\frac{30+4q}{q}\)

= \(\frac{30+4(28)}{q}\)

=\(\frac{142}{28}\)

= 5.07 dollars

bii.

At 45 units

Average cost = \(\frac{Total Cost}{Quantity}\)

NOTE: TC = C = 30 + 4q

Therefore, AC =\(\frac{30+4q}{q}\)

= \(\frac{30+4(45)}{45}\)

=\(\frac{210}{45}\)

= 4.66 dollars

c.

Marginal cost at 28 units produced = Total cost at 28 units - Total cost at 18 units

=\(\frac{30+4(28)-30+4(18)}{28-18}\)

= \(\frac{142-102}{10}\)

= $4.00

d.

Profit (π) = Total sales at 45 units - Total cost at 45 units

= ($5 x 45) - ( 30 + 4(45))

= 225 - 210

= $15.00

e.

Fixed cost is zero. Fixed cost is a cost that does not change, i.e when q = 0 then C = 30 +4(0)

= C = 30 + 4(0)

= 30 + 0

= $30

Correct Answer: A) Input

Explanation

A computer keyboard is a device that is used to input data into a computer. This means that it is used to enter information, such as text, numbers, and commands, into a computer system. Therefore, the correct answer to this question is Option A: Input.

On the other hand, output devices are used to display or present data that has already been processed by the computer. Examples of output devices include monitors, printers, and speakers.

Software refers to the programs and applications that run on a computer system, while storage devices are used to store data, such as hard drives and USB flash drives.

Finally, processing devices are responsible for carrying out instructions and performing calculations in a computer system. This includes the central processing unit (CPU) and graphics processing unit (GPU).

To summarize, a computer keyboard is an input device that is used to enter data into a computer system.
