Let Y(sub-1) be the sales during month t (in thousands of dollars) for a photograph studio, and let P(sub-t) be the price charged for the portraits during month t. The data are included in the file provided below.

Use regression to fit the following model to these data:

The equation indicates that last month's sales and the current month's price are explanatory variables. The last term, e(sub-1), is an error term.
