The cost of sending an overnight package from Kansas City to Miami is $23.50 for a package weighing up to but not including 1
Dimas [21]

Answer:

For every pound that the package weight increases, the price of sending it increases by $3.80.

Step-by-step explanation:

The coefficient 3.80 multiplies the variable x (package weight), so if x is 1 pound the cost increase $3.80, if x is 2 pound the cost increase 2*3.80 = $7.6, and so on.  Generally speaking, for every pound that the package weight increases the cost increases by $3.80.
