Question: 1. The demand function for Good X is defined as Qx = 75 - 2Px - 1.5Py where Py is the price of Good Y.

1. The demand function for Good X is defined as Qx = 75 - 2Px - 1.5Py where Py is the price of Good Y. Calculate the price elasticity of demand using the point formula for Px = 20 and Py = 10. Determine whether demand is elastic, inelastic, or unit elastic with respect to its own price and whether Good Y is a substitute or a complement with respect to Good X.
