Answer:
8
Step-by-step explanation:
√(64)
It will take (100 -28.5)/14 ≈ 5.107 years to get to 100,000 miles. In that time the car will depreciate by a factor of 0.85^5.107, about 0.43605. The value at that time will be
.. $8200*0.43605 ≈ $3706
_____
The difference between 100k miles and 28.5k miles is 71.5k miles. It is "used up" at the rate of 14k miles per year, so the time it takes to do that is 71.5/14 ≈ 5.1 years.
Each year the car depreciates 15%. That is, its value is multiplied by 1 -15% = 0.85. In 5.1 years, the original value will be multiplied by 0.85^5.1. (Remember, exponentiation is repeated multiplication.)
