Using the supply and demand functions below, derive the demand and supply curves if Y=$55,000 and pc = $99. What is the equilibrium price and quantity of coffee?

The demand function for coffee is 

Q = 8.5 − p + 0.01Y, 

where Q is the quantity of coffee in millions of pounds per year, p is the price of coffee in dollars per pound, and Y is the average annual household income in high-income countries in thousands of dollars.

The coffee supply function is 

Q = 9.6 + 0.5p - 0.2pc,

where pc is the price of cocoa in dollars per pound. 

The equilibrium price of coffee is p = $0.97 per pound and the equilibrium quantity is Q = 8.09 millions of pounds per year.
