I have attached the question that I need help with

A regression analysis on predicting sales (in $1000) by using advertising (in $) resulted in the following least squares line: = 80,000 + 5x. This implies that an: O A. increase of $1 in advertising is expected, on average, to result in an increase of $80,005 in sales 0 B. increase of $5 in advertising is expected, on average, to result in an increase of $5,000 in sales 0 C. increase of $1 in advertising is expected, on average, to result in an increase of $5 in sales 0 D. increase of $1 in advertising is expected, on average, to result in an increase of $5,000 in sales
