$P = 7000 {(1 + 0.05)}^{- 12}$

Step 1

Add $1$ and $0.05$ .

$P = 7000 \cdot {1.05}^{- 12}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$P = 7000 \cdot \frac{1}{{1.05}^{12}}$

Step 3

Raise $1.05$ to the power of $12$ .

$P = 7000 \cdot \frac{1}{1.79585632}$

Step 4

Divide $1$ by $1.79585632$ .

$P = 7000 \cdot 0.55683741$

Step 5

Multiply $7000$ by $0.55683741$ .

$P = 3897.86192724$
