Counter Sales	0.2	001
Drive-through Sales	0.3	0.01
pizza Vs. Caf	0.5	0.81
Burger Vs. Caf	0.4	0.02

Select one:

b. Pizza store is insignificant and we need to delete the pizza store data

c. Keep all the variables in the model

d. Pizza stores and Cafe are insignificant and wee need to take them out from the model
