    Answer:

    Pizza parlor’s profit = $515.344

    Step-by-step explanation:

    Given that:

    Linear regression line for pizza parlor’s profit

    y = 2.009x – 37.131

    x represents the number of pizzas sold

    y represent the profit in dollars

    Profit for 275 pizzas

    Putting x = 275 in given equation

    y = 2.009(275) – 37.131

    y = 552.475 – 37.131

    y = 515.344

    Hence,

    Pizza parlor’s profit = $515.344
