Someone me on this
plz show work

This equation is known as the equation for exponential growth/decay:


Since the car is worth no more than $1,900 when bought, we can rewrite the above equation as:


a is the initial value, and b is the growth factor, x is the amount  of time that passes.

So, we can plug in all that information (it's negative because the car's value goes down):


That's your final answer^.
