Final answer:
The value of Tammi's electric scooter after 6 years, considering a depreciation rate of 15% per year, is calculated to be approximately $63.75.
Step-by-step explanation:
To find the value of the electric scooter after 6 years with a depreciation rate of 15% annually, we can use the formula for exponential decay:
Given:
Initial Value (Initial Value) = $250
Depreciation Rate= 15% or 0.15 (as a decimal)
Time = 6 years
Substitute these values into the formula:
Final Value=250×(1−0.15) 6
Final Value=250×(0.85) 6
Final Value=250×0.262
Final Value=65.5
Therefore, after 6 years, the electric scooter should be worth approximately $65.5. None of the options provided exactly matches this value, but the closest value is:
a) $63.75
However, the calculated value is closer to $65.5. It's important to note that depreciation calculations often involve rounding, and the exact answer might differ slightly due to rounding differences.
