The toy rocket hits the ground when h(t) = 0.
So, h(t) = 0 = -9t^2 + 81.
Solving the equation,
-9t^2 = -81
Dividing by -9
t^2 = 9
Taking the square root.
t = 3
The answer is 3 seconds.

have a great day!!
You have to multiply the original price by 1/3 and then multiplying it by 2:
y=1/3x(2)
y=1/3(28.5)(2)
y=9.50(2)
y=19
$19.5
This is 2/3 of the original price (1/3 off).
Hope I helped...
