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.
$0.
$12.
$24.
$6.
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?
1.
210.
218.
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:
$1,200.
$20.
$100.
$1,300.
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.

Growth rate of:

percent.
