Elasticity:
The demand curve is Qd = 500 -2Px
a: What is the intercept value on the Price axis?
b: At what value does the curve cross the Quantity axis?
c: What is the Total Revenue function?
hint: TR = Price X Quantity. The given demand curve gives you an equation for Quantity. Use it to find an equation for Price.
c: If the marginal revenue function is MR = 250-Q, then what are the Price and Quantity values at Equilibrium?
