Making predictions using size and bedrooms

Say you want to predict the price of a house using this model and you know it has:

1000 square feet of living space, and
3 bedrooms

What is your prediction both in log10 dollars and then dollars?

The regression model from the previous exercise is available in your workspace as model_price_2.

> get_regression_table(model_price_2)
# A tibble: 3 x 7
