Im very lost Where did I go wrong I solved for the following

I\'m very lost. Where did I go wrong? I solved for the following for the problem listed below:

b=For every square foot, the predicted price of a home increases by 92.61, holding number of bedrooms and bathrooms constant.

c = 18,155,14.98 or

Predicted price = 1,26715.08 + 92.61 sqft + 11,947.04 beds + 91,777.89 baths

Predicted price = 1,26715.09 + 92.61 (1,923) + 11,947.06 (3) + 91,777.89 (2)

Predicted price = 18,155,014.98

A realtor in Arlington, Massachusetts, is analyzing the relationship between the sale price of a home (Price), its square footage (Sqft), the number of bedrooms (Beds), and the number of bathrooms (Baths). She collects data on 36 recent sales in Arlington in the first quarter of 2009 for the analysis.

My Answers are listed below but I\'m very lost.

She estimates the model as Price = ?₀ + ?₁Sqft + ?₂Beds + ?₃Baths + ? and obtains the following output.

Predict the price of a 1,957 square-foot home with four bedrooms and three bathroom(s). (Round your intermediate calculations and final answer to 2 decimal places.)
