$f(x)=a(1+b)^x$

Where

$f(x)$ is the final price after $x$ years

$a$ is the initial price

$b$ is the rate in decimal form

$x$ is the time in years

We know from our problem that the initial price is $190, so $a=190$ . Now to convert the rate, 15%, to decimal form, we are going to divide it by 100%, so $r=\frac{15}{100} =0.15$ . Let's replace the values:
