Assume the initial value of a car is \$18,000 and that the car's value depreciates. The value of the car can be modeled with an exponential function, V = Iekt, where V is the value of the car at year t, I is the initial value of the car, and k is a constant. Find the number of years it would take for the value of the car to be half the initial value if k is equal to -0.038. Round the answer to the nearest hundredth
