Han creates a scatter plot that displays the relationship between the number of items sold, x, and the total revenue, y, in dollars. Han creates a line of best fit and finds that the residual for the point (12,1,000) is 75. The point (13,930) has a residual of -40. Interpret the meaning of -40 in the context of the problem.
