Let Qs = -1000 + 5.5P and Qd = 25000 2.5P be the supply and demand relationship

Let Qs = -1000 + 5.5P and Qd = 25000 2.5P be the supply and demand relationships respectively for a competitive market.1.Derive the value of the slope for the demand curve.2.Solve for the equilibrium price and quantity. Assume the price is expressed in dollars and the quantity is defined in 1000s of units.3. Calculate the exact quantity demanded and the exact quantity supplied at a price of $2000. If there is a surplus or shortage specify which and calculate its exact value. (Note: quantity is defined in 1000s of units.)show all of your calculations in the space provided.Please show all of your calculations step by step.
