Question- Suppose the demand and supply curves for solar panels in the US are given by the following equations:

Q_DUSA = 190 - 40 P (which can also be written as P = 4.75 - (1/40) Q_DUSA)

Q_SUSA = 40 P - 110 (which can also be written as P = 2.75 + (1/40) Q_SUSA)

where Q_D is the quantity in GW (gigawatts) of solar panels Americans would like to buy; Q_S is the quantity in GW (gigawatts) of solar panels American firms would like to sell; and P is the price per watt generated by solar panels. Assume that firms in the solar panel market are price takers; that is, assume that the solar panel market is a perfectly competitive market.

Problem 3A: Fill in the following table:

Price	Quantity Demanded (QDUSA)	Quantity Supplied (QSUSA)
$2.75
$3.00
$3.25
$3.75
$4.25
$4.75

Problem 3Bi: Using the information in the table, what is the equilibrium price?

[Note: Please answer as just a number. For example, $0.99 would be written as 0.99 without a dollar sign.]

Problem 3Bii: Using the information in the table, what is the equilibrium quantity?

[Note: Please answer in GW (gigawatts) without the label. For example, 100 GW (gigawatts) would be written as 100.]

Problem 3C: Graph the demand and supply curves identifying (1) both the supply and demand curves, (2) the equilibrium price, and (3) the equilibrium quantity.

If the world price per watt generated by solar panels is $3.00, illustrate on your graph above and answer the following questions:

Problem 3Di: What is the quantity in GW (gigawatts) of solar panels that American firms would be willing to sell at that price?

[Note: Please answer in GW (gigawatts) without the label. For example, 100 GW (gigawatts) would be written as 100.]

Problem 3Dii: Is there an excess of supply or an excess of demand?

	a	Excess of supply
	b	Excess of demand

Problem 3Dii: What quantity in GW (gigawatts) of solar panels will Americans export or import?

[Note: Please answer in GW (gigawatts) without the label. For example, 100 GW (gigawatts) would be written as 100.]

In February 2018, President Trump unveiled tariffs on solar cells and panels. These tariffs tax non-American produced solar panels increasing the price from the world price per watt generated by solar panels of $3.00 to $3.25 for Americans.

Problem 3Ei: Following the implementation of the tariffs, what quantity in GW (gigawatts) of solar panels would Americans like to buy?

[Note: Please answer in GW (gigawatts) without the label. For example, 100 GW (gigawatts) would be written as 100.]

Problem 3Eii: Following the implementation of the tariffs, what quantity in GW (gigawatts) of solar panels would American firms like to sell?

[Note: Please answer in GW (gigawatts) without the label. For example, 100 GW (gigawatts) would be written as 100.]
