Algebra-1

1. Determine the number of halving periods:

Since the car's price halves every year and we want to know its value after 5 years, the number of halving periods  is equal to the number of years, which is .

2. Use the exponential decay formula:

The formula for exponential decay in this case is , where:

 is the final value of the car.

 is the initial value of the car. Here, .

 is the number of halving periods, which is .

3. Substitute the values into the formula:...
