First you add 87 +89 which equals 176.
second you multiply all the numbers you want to divide, which, to save time, equals 69,120
176 / 69,120 = 0.0025462962963 (0.003 if needing to round)
When it hits the ground, then h=0
find the xintercept or in this case the tintercepts
c=76
v=135
h=-16t^2+135t+76
use quadratic formula
ax^2+bx+c=0
x=

a=-16
b=135
c=76
x=

x=

x=

aprox
x=-0.5297 or 8.967
exclude the negative root since you can't have negative time
means that it takes 8.97 seconds to hit the ground
Dory: $11.25= x+x+x+y+y+y or $11.25= (3*x)+(3*y)
Nemo: $10.00=x+x+x+x+y+y or $10.00= (4*x)+(2*y)
