Answer

\( P \approx 4252.49 \)

Solution

We start with the equation   6400 = P × (1 + (0.0585/12))^(12·7). Step 1. Isolate P by dividing both sides by (1 + (0.0585/12))^(84):   P = 6400 / (1 + (0.0585/12))^(84). Step 2. Compute the monthly interest rate:   0.0585/12 ≈ 0.004875. Step 3. Rewrite the expression:   P = 6400 / (1.004875)^(84). Step 4. Evaluate (1.004875)^(84). One way is to use logarithms:   ln((1.004875)^(84)) = 84 × ln(1.004875).   Since ln(1.004875) ≈ 0.004863, then   84 × 0.004863 ≈ 0.40888.   Now, (1.004875)^(84) ≈ e^(0.40888) ≈ 1.505. Step 5. Solve for P:   P ≈ 6400 / 1.505 ≈ 4252.49. Thus, rounded to two decimal places, the solution is:   P ≈ 4252.49.

To solve for \( P \) in the equation \( 6400 = P\left(1+\frac{0.0585}{12}\right)^{12 \cdot 7} \), we first need to calculate the term inside the parentheses. 1. Calculate \( \frac{0.0585}{12} \) which is approximately \( 0.004875 \). 2. Therefore, \( 1 + 0.004875 \) equals approximately \( 1.004875 \). 3. Next, raise \( 1.004875 \) to the power of \( 12 \cdot 7 = 84 \): \[ (1.004875)^{84} \approx 1.4645 \] (using a calculator). Now, substitute back into the equation to isolate \( P \): \[ 6400 = P \times 1.4645 \] Now, divide both sides by \( 1.4645 \): \[ P = \frac{6400}{1.4645} \approx 4366.75 \] Thus, the value of \( P \) is approximately \( 4366.75 \) (rounded to two decimal places).
