Answer:
⇒ The constant value that has been given = $45 per day
Step-by-step explanation:
The cost y to rent a car is given to be $45 per day
Also, The cost includes 22 percent of total miles driven
Now, Total miles driven is a variable as the miles to be driven is not fixed
So, as a result cost per mile is also not a constant
But, The cost to rent per day is fixed and that is given to be $45 per day.
So, in any conditions this is going to be fixed
⇒ The constant value that has been given = $45 per day
