The equation y=−24+335x−133 represents the average number of visitors (in thousands) per day to a park area where x represents the month of the year. Use this model to predict the average daily attendance at the park for the month of March. (Hint: March is the third month.)
JUst put '3' where 'x' is in the equation:
Attendance (in thousands)March=3 = -24(32) + 335(3) -133 ( Because I think you left off x^2 for the -24 part)
= -24(9) = 335(3) - 133 = ............ thousand
