Bob would like to remove three trees from his level, wooded back yard. He saved $1,000 but is
unsure if he has enough money to remove all three trees. So Bob contacts a local tree remova
company, Chopper Tree Service, to get some pricing information:
Chopper Tree Service pricing

Large Trees
(50-90 feet)
Tree Removal

$9 per foot
$10 per foot
Stump Grinding

$150
$300
When calculating the height of the trees, round up to the next whole number of feet.
If the cost to remove all trees is more than $1,200 we will grind your stumps for free.
1. Bob needs to estimate the height of each tree to determine if he has enough money to
pay Chopper Tree Service to remove them. Bob uses a clinometer* to measure the angle
of elevation to the top of the tree. He holds the clinometer 6 feet from the ground.

"...clinometer is an instrument for measuring angles of slope (or tilt), elevation or depression of an object with
respect to gravity. Clinometers measure both inclines (
positive slopes, as seen by an observer looking upwards) and
observer looking downward).
