A.

Average fixed costs

B.

Average variable costs

C.

Fixed costs

D.

Variable costs

Correct answer is C

Examples of general and administrative expenses are:

  • Consulting expenses.
  • Corporate management wages and benefits (such as for the chief executive officer and support staff)

 Fixed costs are those costs that must be incurred in fixed quantity regardless of the level of output produced.

Given that FC = N500, VC = N1,500, and Q = 50 units. Find the average cost of the product.

A.

N30

B.

N40

C.

N10

D.

N20

Correct answer is B

The Average Cost is the per unit cost of production obtained by dividing the total cost (TC) by the total output (Q). Thus we have;
Average cost = Total cost ÷ Total output(quantity)

Total cost = fixed cost + variable cost

Average cost = 500 + 1500 ÷ 50
2000 ÷ 50 = 40
