Reference no: EM131055664

Question 1.) You are given the following supply and demand curve functions for a market for sunglasses.

Q_D = -2(P) + 340

Q_S = 5P - 150

Graph the following:

The demand curve;

The supply curve;

Consumer surplus;

Producer surplus;

Total surplus;

The equilibrium price and quantity; and,

Total revenue for this market.

Using the functions above, the following table is found. Please complete this table.

Price	Quantity Demanded	Quantity Supplied	Total Revenue	Fixed Cost	Variable Cost	Total Cost	Marginal Cost	Average Total Cost	Average Fixed Cost	Average Variable Cost	Profit	Marginal Revenue
$0	340	0	$0	$150	$0		-	-	-	-	-	-
$40		50				$290				$2.80	$10,110	-$130
$50	240		$12,000	$150		$310	$0.40	$3.10	$1.50	$1.60
$60		150			$210	$360	$1.00				$12,840
$70			$14,000	$150		$480		$2.40	$0.75			-$40
$100	140	350		$150	$710		$2.53			$2.03		$0
$120	100				$970	$1,120		$2.49	$0.33		$10,880

Please graph the following using the previous table:

Marginal cost;

Average total cost;

Average fixed cost;

Marginal revenue; and,

Average variable cost.

Question 2.) If a price floor of $100 is imposed, what will happen within this market? Please graph the results and explain.

Question 3.) Suppose a consumer report comes out stating that sunglasses will decrease the risk of cataracts by 20 percent if worn during peak sun hours regularly. What may happen in the market for sunglasses? Please draw and explain the change in the graph. Using the previous table, select a new price and quantity supplied. (Hint: Think about your factors of supply and demand, which curve will shift if a curve shifts. Graph this first before selection a new P and Q from above). You know Qs = Qd at equilibrium, so if you are looking for:

Q_d= -2P + x

Graph the following:
The original supply curve;
The original demand curve;
The original price at equilibrium;
The original quantity at equilibrium;
The new demand curve;
The new price at equilibrium;
The new quantity at equilibrium;
The original consumer surplus;
The new consumer surplus;
The original producer surplus;
The new producer surplus;
The original total surplus;
The new total surplus.

What is the change in total revenue under the new demand?

Question 4.) What happens if a $7 tax is imposed on sunglasses, find the equation for Q_STax. Solve for the following items (USE YOUR NEW DEMAND EQUATION FROM QUESTION 3!!!):

The price buyer's pay under the tax;
The quantity buyers will purchase at the price under the tax;
The price seller's receive under the tax for that quantity;
The new producer surplus under tax;
The new consumer surplus under tax;
The new tax revenue received;
The new total surplus under tax; and,
The deadweight loss.

Use the new demand function found in Question 3 to solve as your Q_d function. Please be sure to graph everything as well.
