The demand curve and supply curve for one-year discount bonds were estimated using the following equations:

Bd: Price = -2/5Quantity + 990

Bs: Price = Quantity + 500

As the stock market continued to rise, the Federal Reserve felt the need to increase the interest rates. As a result, the new market interest rate increased to 19.65%, but the equilibrium quantity remained unchanged. What are the new demand and supply equations? Assume parallel shifts in the equations.
