1. **State the problem:**
A vintage car was valued at 650000 five years ago. For the first 3 years, its value depreciates by 2% per year compounded annually. For the next 2 years, its value increases by 5% per year compounded annually. We need to find the current value of the car.
2. **Formula for compound interest/depreciation:**
The value after $n$ years with an annual rate $r$ (expressed as a decimal) is given by:
$$ V = P(1 + r)^n $$
where $P$ is the initial value.
3. **Calculate depreciation for the first 3 years:**
The depreciation rate is 2%, so $r = -0.02$.
Initial value $P = 650000$.
$$ V_3 = 650000(1 - 0.02)^3 = 650000(0.98)^3 $$
Calculate:
$$ (0.98)^3 = 0.98 \times 0.98 \times 0.98 = 0.941192 $$
So,
$$ V_3 = 650000 \times 0.941192 = 611774.8 $$
4. **Calculate appreciation for the next 2 years:**
The appreciation rate is 5%, so $r = 0.05$.
Starting value after 3 years is $V_3 = 611774.8$.
$$ V_5 = 611774.8(1 + 0.05)^2 = 611774.8(1.05)^2 $$
Calculate:
$$ (1.05)^2 = 1.1025 $$
So,
$$ V_5 = 611774.8 \times 1.1025 = 674784.3 $$
5. **Final answer:**
The current value of the car after 5 years is approximately **674784.3**.
