The business manager for the local baseball team uses a scatter plot to show that as the team's losses increase the sales in concessions decrease. The equation of the line of best fit for his data is y = -2.5x + 82.5, where x is the number of losses and y is the concession sales in thousands of dollars. Point t shows that the concession sales totaled $55,000 when the team experienced its 12th loss. Which is the value of the residual at this data point?
