Suppose the production function is given by Q = 5K + 3L. What is the average product of capital when 10 units of
capital and 10 units of labor are employed?

Consider a market characterized by the following inverse demand and supply functions:
PX = 30 – 3QX and PX = 10 + 2QX. Compute the surplus consumers receive when a $24
per unit price floor is imposed on the market.
Suppose the demand for good X is given by Qxd = 10 - 2Px + Py + M. The price of good X is $1, the price of good Y is
$10, and income is $200. Given these prices and income, how much of good X will be purchased?
None of the statements associated with this question are correct.
Suppose market demand and supply are given by Qd = 100 – 2P and QS = 5 + 3P. If the government sets a price floor
of $20 and agrees to purchase all surplus at $20 per unit, the total cost to the government will be:
Suppose demand is given by Qxd = 25 ? 5Px + 2Py + Ax, where Px = $10, Py = $5, and Ax = $100. What is the
advertising elasticity of demand for good x?


For a cost function C = 100 + 5Q + 2Q2, the average variable cost of producing 10 units
of output is:
10.None of the answers are correct.
Suppose the demand for X is given by Qxd = 100 – 2PX – 4PY + 10M + 2A, where PX represents the price of good X,
PY is the price of good Y, M is income, and A is the amount of advertising on good X. Based on this information, we
know that good X is a:
substitute for good Y and a normal good.
complement for good Y and an inferior good.
complement for good Y and a normal good.
substitute for good Y and an inferior good.
You’ve recently learned that the company where you work is being sold for $300,000. The company’s income
statement indicates current profits of $11,000, which have yet to be paid out as dividends. Assuming the company will
remain a “going concern” indefinitely and that the interest rate will remain constant at 9 percent, at what constant rate
does the owner believe that profits will grow?
Instruction: Round your response to 2 decimal places.

The supply curve for product X is given by QXS = -520 + 20PX .
a. Find the inverse supply curve.




b. How much surplus do producers receive when Qx = 400? When Qx = 1,200?

When QX = 400: $

When QX = 1,200: $
A firm produces output according to a production function:
Q = F(K,L) = min {2K,4L}.
a. How much output is produced when K = 2 and L = 3?

b. If the wage rate is $30 per hour and the rental rate on capital is $10 per hour, what is the cost-minimizing input mix
for producing 4 units of output?
