Sally sells cookies and offers to deliver them to her neighbors. She charges a fixed fee and a constant amount per dozen cookies she delivers. Some of the delivery charges based on the dozens of cookies are shown in the table below.
Function D models the delivery charge, D(x), Sally charges to deliver x dozen of cookies. Why does D(0) not make sense in the context of this scenario?
What is...
It does not make sense for us to charge someone a delivery fee for delivering 0 cookies since they aren't getting anything.
