We are given that the amount $37184 will increase by a percentage of 6% every year. This can be modeled using an equation of exponential growth, which follows the next function:


y=P_0(1+r)^t

Where:


\begin{gathered} P_0=\text{ initial value} \\ r=\text{ growth rate} \\ t=\text{ time} \end{gathered}

The initial value is:


P_0=37184

The growth rate must be in decimal form. To obtain the decimal form we divide the percentage rate by 100:


r=(6)/(100)=0.06

Now, we substitute the values:


y=37184(1+0.06^{})^t

Now, we solve the operations inside the parenthesis:


y=37184(1.06)^t

Now, we substitute the value of "t = 13", we get:


y=37184(1.06)^(13)

Solving the operations:


y=79311

Therefore, her salary in 13 years will be $79311
