Please tag the relevant programming language and the course name.

Answer 2

/*
The fee is calculated based on the following price structure:
- the first 5 hours are billed at $1 per hour.
- after that, each hour is billed at $0.5 per hour.
- for each 24 hours, there is a flat fee of $15.
*/

Consider the following case:
I park my 🚗 for 4 hours. Hence I should pay $4.
According to your code, I would only need to pay
b = 4%24 = 4
t = (4–4)*15 + 4*0.5 = 2
