Question

You buy a new smartphone for $700 and sell it 2 years later for $185. Assume that the resale value of the smartphone decays exponentially with time. Write an equation that represents the resale value V (in dollars) of the smartphone as a function of the time t (in years) since it was purchased.

Answer 1

The equation that represents the resale value V (in dollars) of the smartphone as a function of the time t (in years) since it was purchased is:

V = 700e^(-0.2t)
