Find a quadratic regression equation for the price-demand data, using x as the independent variable.
p= a + bx + cx2
Round a to the nearest integer, round b to 2 decimal places, and round e to 4 decimal places.
Revenue Model
Using the regression model computed above, find a model for the weekly revenue, using a as the
independent variable.
NOTE: Do not calculate another regression. Use the price equation to find a model for revenue
R(x) = p ax.
