Answer:

  • exponential
  • $57.25

Step-by-step explanation:

a) Each year, the price is multiplied by (1 - 14%) = 0.86. After t years, the price will be 0.86^t times what it was in the beginning. This function is an exponential function.

__

b) After 3 years, the price will be ...

  $90×0.86^3 ≈ $57.25
