Total price paid : 86=12*X+10*Y
Total number of people : 8=X+Y
Hence Y=8-X thus 86=12*X+10(8-X) => 86-80=2X => X=3 => Y=5

The potential energy is converted into kinetic energy.
Therefore, for conservation of energy we have:
mgh = (1/2) m * v ^ 2
From here we clear the speed:
v = root (2 * g * h)
The height will then be:
h = v ^ 2 / (2 * g)
Substituting the values:
h = (34) ^ 2 / (2 * (32))
h = 18.0625 feet
Answer: The pear before it fell was 18.0625 feet up in the tree.
