Suppose the linear regression line y= 2.009x - 37.131 predicts a pizza parlor's profits based on the number of pizzas sold. If x represents the number of pizzas sold, and y represents the pizza parlor's profits in dollars, about how much can the pizza parlor expect in profits if it sells 275 pizzas.
The profit that can be expected by the pizza parlor is calculated by substituting 275 to the x of the given equation. That is, y = 2.009x - 37.131 y = 2.009(275) - 37.131 y = 515.344 Thus, the answer to this item is letter B.
