The cell phone experiments an exponential depreciation, which is defined by the following formula:
, for . (1)
Where:
- Initial cost, measured in monetary units.
- Depreciation rate, no unit.
- Time, measured in years.
- Current value of the cell phone, measured in monetary units.
If we know that and , then the exponential decay function that represents the situation is:
Which means that correct answer is 1.
