Question

Suppose the linear regression line y = 4.009x - 77.531 predicts a pizza a

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 325 pizzas?

Answer 1

$1,225.394

Explanation:

We know that...

x = pizzas sold

and

y = profits

In this case, we are searching for the expected profits (y) of pizzas when we sell 325 (x). All we have to do is plug this in the equation given.

4.009(325) - 77.531 = 1225.394

So y or our profit, is $1,225.394
