Final Answer:
After five years, the value of Anya's car will be £8,228.
Step-by-step explanation:
Anya's car depreciates at a rate of 12% per year. To calculate the depreciation over five years, we can use the formula for exponential decay:
is the value after (t) years,
is the initial value, \(r\) is the rate of depreciation as a decimal, and (t) is the time in years.
In this case, Anya's initial investment
is £12,500, the rate of depreciation (r) is 12% or 0.12, and the time (t) is 5 years. Plugging these values into the formula, we get:
![\[V_5 = £12,500 * (1 - 0.12)^5\]](https://img.qammunity.org/2021/formulas/mathematics/high-school/au4e61rwlrnf4pie4fdw0e51k252vqdj0b.png)
![\[V_5 = £12,500 * (0.88)^5\]](https://img.qammunity.org/2021/formulas/mathematics/high-school/c5666pd3ekn40vt6ogwd7gf60uibkrbewa.png)
![\[V_5 ≈ £8,228\]](https://img.qammunity.org/2021/formulas/mathematics/high-school/egnqlobalrfminkx2fh4rf8kz01v670ihi.png)
Therefore, after five years, the value of Anya's car will be approximately £8,228.
It's important to note that exponential decay models assume a continuous and constant rate of depreciation. In the context of this problem, it means that the car's value decreases by 12% each year without any fluctuations. This mathematical approach provides a straightforward method for calculating depreciation over time. Anya can use this information to estimate the future value of her car and plan accordingly for potential resale or replacement.
