What mathematical algorithm can be applied?

Question

Python

Hello, I'm taking a python course.
Help solve the problem.

I need to calculate the cost of a car, the task is:
"A new car costs = 10,000
a car with an age of 40 years = 0"

Which equation algorithm should I use?

Answer 1

minusCostPerDay = 10000 / (365 * 40)
costAfter1Day = 10000 - minusCostPerDay
costAfter1Year = 10000 - 365 * minusCostPerDay
You can also factor in leap years for greater accuracy. What is the algorithm, I heze. This is the third grade of the general education school.

Answer 2

Linear regression is
