We have a function of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: decrease rate
 t: time
 Substituting values we have:
 y = 3250 * (0.915) ^ t
 After 4 years we have:
 y = 3250 * (0.915) ^ 4
 y = 2278.07 $
 Answer:
 The equation of the exponential equation is:
 y = 3250 * (0.915) ^ t
 the four-wheeler will be worth in 4 years about:
 y = 2278.07 $
