Explanation of Solution

Since q = 40,000 has been produced with 5×2=10units of capital and 5×1=5unit of labor. However, substitutability is not allowed by the production technology. Thus, the production function took the shape of a flexographic curve as shown below:

Explanation of Solution

Production functions are given below:

q=5,000×k=5,000×lq=8,000×2l=8,000×k

When lawn is cut by 1st method:

k=l=20,0005,000=4

When lawn is cut by 2nd method:

l=20,0008,000=2.5k=2l=2×2.5=5

Total capital requirement = 9

Total labor requirement = 6.5

Production functions are given below:

q=5,000×k=5,000×l

q=8,000×2l=8,000×k

When lawn is cut by 1st method:

k=l=10,0005,000=2

When lawn is cut by 2nd method:

l=30,0008,000=3.75

k=2l=2×3.75=7.50

Total capital requirement = 9.5

Total labor requirement = 5.75

The fraction of K and L means the amount of capital input used per unit of labor.

This table shows the resources uses in the Large Mowers and Small Mowers.

Explanation of Solution

Calculation of labor and capital when 40000 square foot of lawn is cut by 1st method with p fraction.

k=l=40,000p5,000=8p

Calculation of labor and capital when (1-p) fraction of 40,000 square foot lawn is cut by 2nd method.

l=40,000(1p)8,000=5(1p)

k=2l=2×(1p)=10(1p)

Calculation of labor requirement:

l=8p+55p=5+3p

Calculation of total capital requirement:

k=8p+1010p=102p

Two equations are given as follows:

l=5+3pk=102p

Solving first equation for p and putting the value of p in second as shown below:

l=5+3pl5=3pp=l53k=102(l53)=302l+103=402l3

The Table shows the different calculations of Labor (L) and capital (K) in Small Mowers as shown below:

The following graph plots daily cost curves for a firm operating in the competitive market for sweatbands. Hint: Once you have positioned the rectangle on the graph, select a point to observe its coordinates.   Profit or Loss0246810121416182050454035302520151050PRICE (Dollars per sweatband)QUANTITY (Thousands of sweatbands per day)MCATCAVC8, 30   In the short run, given a market price equal to $15 per sweatband, the firm should produce a daily quantity of     sweatbands.   On the preceding graph, use the blue rectangle (circle symbols) to fill in the area that represents profit or loss of the firm given the market price of $15 and the quantity of production from your previous answer. Note: In the following question, enter a positive number regardless of whether the firm earns a profit or incurs a loss. The rectangular area represents a short-run     of    thousand per day for the firm.
