Suppose that for a particular firm the only variable input into the product process is labor and that output equals zero when no workers are hired. in addition, suppose that marginal cost of the third worker hired is $40, and the average total cost when three workers are hired is $50. what is the total cost of production when three workers are hired?

The correct answer is $150.

Explanation:  

We know that the marginal cost of hiring a third worker is $ 40. And that the average total cost when 3 workers are hired is $ 50. The average total cost formula is:

Average total cost = (total cost) ÷ (number of workers)

Then we solve the equation in 3 steps:

1) $ 50 = X ÷ 3

2) $ 50 × 3 = X

3) $ 150 = X

We can diagram the workers cost chart

Number of workers - Marginal cost - Total cost

              1                -         $60         -     $60

              2               -         $50         -     $110  

              3               -         $40         -     $150

answer with step-by-step explanation:

a. wx is perpendicular to xy - true:

(since x is adjacent to x and y and all angles are 90 degrees in a square, therefore wx is perpendicular to xy)

b. ∠w is congruent to ∠x - true:

(all angles in a square are equal to each other)

c. ∠w is supplementary to ∠x - true:

(∠w and ∠x both are right angles which add up to 180 degrees so they are supplementary angles)

d. wxyz is a rhombus - true:

(a rhombus has all sides equal in length and so has a square so it is a rhombus)

e. wxyz is a trapezoid - false:

(a trapezoid has only one pair of parallel sides while a square has two pairs of parallel sides)

f. wx is parallel to yz - true:

(wx and yz are parallel to each other)
