The demand function for Newton's Donuts has been estimated as follows:
Qx = -14 - 54Px + 45Py + 0.62Ax
where Qx represents thousands of donuts; Px is the price per donut; Py is the average price per donut of other brands of donuts; and Ax represents thousands of dollars spent on advertising Newton's Donuts. The current values of the independent variables are Ax=120, Px=0.95, and Py=0.64.
