23-64) Let Yt be the sales during month t (in thousands of dollars) for a photography studio, and let Pt be the price charged for portraits during month t. The data are in the file P11_45.xlsx. Use regression to fit the following model to these data:

Y_t = a + b₁Y_t?1 + b₂Pt + e_t

This equation indicates that last month's sales and the current month's price are explanatory variables. The last term, et, is an error term.

If the price of a portrait during month 21 is $10, what would you predict for sales in month 21?
