Answer 2

The expected sales is $655.

Explanation:

The given regression line is

`y=2.1x+130`

Where, x represents the dollars spent in advertising, and y represents the company sales in dollars.

If company spends $250 in advertising, then the expected sales of company is

`y=2.1(250)+130`

`y=525+130`

`y=655`

Therefore, the expected sales is $655.
