The tax rate is 5%
Hope this helps!
Think about it think 6x5 or higher then you will get you answer by doing that
It hits the ground at h=0
0=-16t^2-16t+96
undistribute -16
0=-16(t^2+t-6)
factor
0=-16(t-2)(t+3)
set to zero
0=t-2
2=t
t+3=0
t=-3, nope, we can't have negative time
at t=2, or 2 seconds
I got 3/8, hope this helps.
