Respuesta :

The pizza parlor can expect a profit of $750 if it sells 275 pizzas.

What is linear regression?

Linear regression is a linear approach that helps in modeling the relationship between a dependent and independent variable.

The linear regression line is given by:

y = 3.009x -77.131

  • It is given that x is the total number of pizzas sold and y is the profit expected.
  • We have to substitute the value of x=275 in the equation.

y = $ (3.009×275) - 77.131

= $ 827.475 - 77.131

= $ 750.344

≈ $ 750

Thus the pizza parlor can expect a profit of $750 if it sells 275 pizzas.  The correct answer is option A.
