A $29,600 Station-wagon Depreciates 11% Per Year. What Is Its Value After 6 Years? Round To The Nearest Dollar.
Introduction
Depreciation is a crucial concept in mathematics, particularly in finance and economics. It refers to the decrease in value of an asset over time due to various factors such as wear and tear, obsolescence, or market conditions. In this article, we will explore how to calculate the value of a station-wagon that depreciates 11% per year, starting with an initial value of $29,600. We will use the concept of exponential decay to determine its value after 6 years.
Understanding Depreciation
Depreciation can be calculated using the formula:
A = P (1 - r)^n
Where:
- A is the final value of the asset
- P is the initial value of the asset
- r is the rate of depreciation (as a decimal)
- n is the number of years
In this case, the initial value of the station-wagon is $29,600, and the rate of depreciation is 11% per year. We need to convert the rate of depreciation from a percentage to a decimal by dividing by 100:
r = 11% / 100 = 0.11
Calculating the Value After 6 Years
Now that we have the initial value and the rate of depreciation, we can plug these values into the formula to calculate the value of the station-wagon after 6 years:
A = 29600 (1 - 0.11)^6
To calculate the value, we need to raise (1 - 0.11) to the power of 6:
(1 - 0.11) = 0.89
0.89^6 ≈ 0.4533
Now, we multiply the initial value by this result:
A = 29600 × 0.4533 ≈ 13419.48
Rounding to the Nearest Dollar
Finally, we need to round the value to the nearest dollar. Since the value is $13,419.48, we round it to $13,419.
Conclusion
In this article, we calculated the value of a station-wagon that depreciates 11% per year, starting with an initial value of $29,600. We used the concept of exponential decay to determine its value after 6 years. The result is a value of $13,419 after 6 years of depreciation.
Example Use Cases
The concept of depreciation is widely used in various fields, including finance, economics, and engineering. Here are a few example use cases:
- Calculating the value of a car after a certain number of years
- Determining the value of a piece of equipment after a certain number of years
- Calculating the value of a building after a certain number of years
- Determining the value of a company's assets after a certain number of years
Formula Derivation
The formula for depreciation is derived from the concept of exponential decay. Exponential decay is a process where the value of an asset decreases over time at a constant rate. The formula for exponential decay is:
A = P e^(-rt)
Where:
- A is the final value of the asset
- P is the initial value of the asset
- r is the rate of decay (as a decimal)
- t is the time (in years)
However, in the case of depreciation, the rate of decay is not a constant rate, but rather a percentage decrease. To account for this, we use the formula:
A = P (1 - r)^n
This formula is derived from the concept of compound interest, where the interest is compounded annually. However, in the case of depreciation, the interest is subtracted annually, resulting in a decrease in value.

Introduction
In our previous article, we calculated the value of a station-wagon that depreciates 11% per year, starting with an initial value of $29,600. We used the concept of exponential decay to determine its value after 6 years. In this article, we will answer some frequently asked questions related to depreciation and exponential decay.
Q&A
Q: What is depreciation?
A: Depreciation is a decrease in the value of an asset over time due to various factors such as wear and tear, obsolescence, or market conditions.
Q: What is the formula for depreciation?
A: The formula for depreciation is:
A = P (1 - r)^n
Where:
- A is the final value of the asset
- P is the initial value of the asset
- r is the rate of depreciation (as a decimal)
- n is the number of years
Q: What is the rate of depreciation?
A: The rate of depreciation is 11% per year in this case.
Q: How do I calculate the value of an asset after a certain number of years?
A: To calculate the value of an asset after a certain number of years, you need to use the formula for depreciation. You need to know the initial value of the asset, the rate of depreciation, and the number of years.
Q: What is the difference between depreciation and amortization?
A: Depreciation is a decrease in the value of an asset over time due to wear and tear, obsolescence, or market conditions. Amortization is a decrease in the value of an intangible asset, such as a patent or a trademark, over time.
Q: Can I use the formula for depreciation for any type of asset?
A: Yes, you can use the formula for depreciation for any type of asset, including cars, buildings, equipment, and intangible assets.
Q: How do I determine the rate of depreciation?
A: The rate of depreciation depends on the type of asset and the market conditions. You can use historical data or industry benchmarks to determine the rate of depreciation.
Q: Can I use the formula for depreciation for assets that appreciate in value?
A: No, you cannot use the formula for depreciation for assets that appreciate in value. The formula is designed for assets that decrease in value over time.
Q: What is the difference between straight-line depreciation and accelerated depreciation?
A: Straight-line depreciation is a method of depreciation where the value of an asset decreases by a fixed amount each year. Accelerated depreciation is a method of depreciation where the value of an asset decreases by a larger amount in the early years and a smaller amount in the later years.
Q: Can I use the formula for depreciation for assets that have a salvage value?
A: Yes, you can use the formula for depreciation for assets that have a salvage value. You need to subtract the salvage value from the initial value of the asset before using the formula.
Conclusion
In this article, we answered some frequently asked questions related to depreciation and exponential decay. We hope that this article has provided you with a better understanding of the concept of depreciation and how to use the formula for depreciation.
