Question

Advantage Airlines has a set fee for each checked bag, plus an additional charge for each pound the bag weighs. The cost is a linear fund of the weight?
What is the rate of change of this function?

Answer 1

Answer:

A 0.50

Step-by-step explanation:

Answer 2

Change in cost = 40 - 25 = 15 dollars

Change in weight = 50 - 20 = 30 pounds

Divide the two results to get 15/30 = 0.5

The rate of change is 0.5 dollars per pound meaning that each time you add a pound, the cost goes up by $0.50 (50 cents)
