Step 1.1

Multiply $50$ by $0.055$ .

$\ln (p) = \ln (105000) + 2.75 x$

Step 2

Move all the terms containing a logarithm to the left side of the equation.

$\ln (p) - \ln (105000) = 2.75 x$

Step 3

Use the quotient property of logarithms, $\log_{b} (x) - \log_{b} (y) = \log_{b} (\frac{x}{y})$ .

$\ln (\frac{p}{105000}) = 2.75 x$

Step 4

To solve for $p$ , rewrite the equation using properties of logarithms.

$e^{\ln (\frac{p}{105000})} = e^{2.75 x}$

Step 5

Rewrite $\ln (\frac{p}{105000}) = 2.75 x$ in exponential form using the definition of a logarithm. If $x$ and $b$ are positive real numbers and $b \neq 1$ , then $\log_{b} (x) = y$ is equivalent to $b^{y} = x$ .

$e^{2.75 x} = \frac{p}{105000}$

Step 6.1

Rewrite the equation as $\frac{p}{105000} = e^{2.75 x}$ .

$\frac{p}{105000} = e^{2.75 x}$

Step 6.2

Multiply both sides of the equation by $105000$ .

$105000 \frac{p}{105000} = 105000 e^{2.75 x}$
