Develop a multiple regression equation with annual income and household size as the independent variables. Estimate and report the estimated model. Discuss your findings.

Can you please outline how the answer is:

The regression equation is :

Amount Charged = 33.133009*Income + 356.295901*Household Size + 1304.904779

I have used the regression equation in excel but get getting different results?!
