1. What will be the predicted sales volume in the city if the price of the frozen pizza was $2.50

If the regression equation is as follows:

Baltimore - Baltimore regression equation = y = 126624.8913- 34955.59942 (Baltimore Price)

Using the regression equation listed above, is this the correct answer to the predicted sales volume if the pizza was 2.50 each?

y = 126624.8913- 34955.59942 (2.50) = 229173.2

So, the predicted Sales volume would be 229173.2 ---- is this correct? If not, any explanation that could help me would be greatly appreciated.
