Please help me I've been stuck forever!! None of the answers on here are right even the verified ones! The value of Sara's new car decreases at a rate of 8% each year.

1. Write an exponential function to model the decrease in the car's value each month.
2. Write an exponential function to model the decrease in the car's value each week.
3. Write an exponential function to model the decrease in the car's value each day.

I turned it in and she said this What you did is wrong! Hint: f(x) = (1-0.08)^ (1/12) ^(12t) which becomes f(x) = (0.993)^ (12t).. You need to do that using 52 and 365 for parts 2 and 3.

I'm lost help
