We are not given tables, so will just use the amortization formula.

where
P=amount to be deposited today, to be found
A=amount withdrawn each year=18000
i=Annual interest=9%
n=number of years = 20
Substituting values,

=164313.82 to the nearest cent
Answer:
The truck have travelled 345.5 inches after 5 rotations of the tires
Step-by-step explanation:
Given:
Diameter of the tyre= 22 inches
Number of rotations= 5
To find:
Distance travelled after 5 rotations=?
Solution:
We have given with diameter,
So let radius be r
r= 

r=11 inches
The distance covered by one rotation is given by circumference
Circumference =
Substituting the values, we get
Circumference =
Circumference =
Circumference =
Circumference =
Circumference = 69.11
Now for 5 rotation,
Distance travelled = 
Distance travelled = 
Distance travelled = 
The truck will travel 345.5 inches.
