Express in words the amount the cab company charges per ride and per mile. (Example: Green Cab Company charges a $3 drop charge or flat rate [the cost of the ride], plus $2 per mile.)

To express the amount a cab company charges per ride and per mile, you typically need to know the base fare or drop charge, which is the cost of the ride, and the charge per mile. For example, let's consider Green Cab Company.

Green Cab Company charges a $3 drop charge or flat rate, which accounts for the initial cost of the ride, regardless of the distance traveled. In addition to the drop charge, they charge $2 per mile for every mile traveled during the trip.

So, to summarize, Green Cab Company charges a $3 drop charge and an additional $2 for every mile traveled.
