Question

Suppose the linear regression line y= 4.009x- 77.531 predicts a pizza parlor's profits based on the number of pizzas sold. If x represents the number of pizzas sold, and yrepresents the pizza parlors profits in dollars, about how much can the pizza parlor expect in profits if it sells 325 pizzas?​

Answer 1

The estimated profit is 62.784

Explanation:

y = 4.009x - 77.531

Plug in the number of pizzas sold for x:

y = 4.009(35) - 77.531 = 140.315 - 77.531 = 62.784

Answer 2

$1225

Explanation:

When you take y=4.009x-77.531

x=325

y=4.009(325)-77.531

Answer would be $1225
