Question 8 of 12 • VA-Mathematical Analysis
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 pound, and $3.80 for each additional pound or portion of a pound. A model for the total cost C (in dollars) of sending the package is C = 23.50 + 3.80, x > 0, where x is the weight (in pounds). What is the meaning of the coefficient 3.80 in the context of the problem?
Answer
A
When the package weighs less than one pound, the price of the package is $3.80.B
For every pound that the package weight increases, the price of sending it increases by $3.80.C
For every pound that the package weight increases, the price of sending it increases by $23.50.D
When the package weighs less than one pound, the price of the package is $23.50.
