We observe that total costs increase from $1,500 to $1,800 when a firm increases output from 40 to 50 units. Which of the follow
iren2701 [21]

Answer:

c. Fixed Cost = $300

Explanation:

Because marginal cost is constant we can find the variable cost per unit and then subtract the total variable cost from the total cost in order to find the fixed cost. The firms total cost increase $300 (from 1500 to 1800) when output increases by 10 units (from 40 to 50), so the variable cost per unit is 300/10=30.

Now to calculate the total variable cost we will multiply variable cost per unit by the number of units.

50*30= 1500

Now we will subtract 1500 from 1800 in order to find the fixed cost.

1800-1500=300

Fixed cost is $300.

How will the increase in government spending financed by borrowing affect national savings?.
Whitepunk [10]

Increament in government spending which is financed by borrowing will most likely affect national savings.

This is because borrowing money means you are spending from your future income.

The negative effect of spending borrowed money will most likely be felt when the money is not used for money yielding ventures.

This means that when borrowed money is not used to boost the economy of a country, it will most likely lead to the depletion of the national savings or reserve.

<h3>Viable areas to utilizing borrowed money</h3>

  • Infrastructure development
  • power
  • Education
  • Health
  • Transportation
  • Research
