The answer you are looking for is 46%
A) a=the initial value ($1650)
b=1-percent of decrease (0.81 or 81%)
B) About 3 years
For this case we have an equation of the form:
![h (t) = (1/2) * (a) * (t ^ 2) + v0 * t + h0 ](https://tex.z-dn.net/?f=h%20%28t%29%20%3D%20%281%2F2%29%20%2A%20%28a%29%20%2A%20%28t%20%5E%202%29%20%2B%20v0%20%2A%20t%20%2B%20h0%0A)
Where,
h0: initial height
v0: initial speed
a: acceleration
Substituting values we have:
![h (t) = (1/2) * (- 32) * (t ^ 2) + 0.25 * t + 12 ](https://tex.z-dn.net/?f=h%20%28t%29%20%3D%20%281%2F2%29%20%2A%20%28-%2032%29%20%2A%20%28t%20%5E%202%29%20%2B%200.25%20%2A%20t%20%2B%2012%0A)
Rewriting we have:
![h (t) = -16t ^ 2 + 0.25 * t + 12 ](https://tex.z-dn.net/?f=h%20%28t%29%20%3D%20-16t%20%5E%202%20%2B%200.25%20%2A%20t%20%2B%2012%0A)
