Suppose gold (G) and silver (S) are substitutes for each other because both serve as hedges against inflation. Suppose also that the supplies of both are fixed in the short run (Qg =60 and Qs=270) and that the demands for gold and silver are given by the following equations:

Pg = 930− Qg +0.50 Ps and Ps = 600− Qs S + 0.50 Pg.

What the the equilibrium prices of gold and silver?

The equilibrium price of gold is$and the equlibrium price of siliver is $. (Enter your responses rounded to two decimal places.)

What if a new discovery of gold doubles the quantity supplied to 120? How will this discovery affect the prices of both gold and silver?

The equilibrium price of gold will be $ and the equlibrium price of siliver will be$.
