(a)
Answer to Problem 27IP
A function to represent the total cost of any number of miles driven is as follows:
Explanation of Solution
Given information:
Money spent by Logan to rent the truck =
Charge of the truck =
Charge of driving the truck per mile =
Calculation:
Let total cost be c.
Let total number of miles bex.
Since the total cost depends upon the number of miles driven, the total cost c is the dependent variable and the number of miles drivenx is the independent variable.
Charge of driving the truck per mile =
A function to represent the total cost of any number of miles driven can be evaluated as follows:
