Answer: Chemical weathering
its the breakdown of rocks
by chemical reactions that change the rocks' makeup, or composition.
51.36 is the answer.
The equation is total=original(1+% in decimal form)
Using an exponential function, it is found that the number 131.5 represents the initial value of the plane, in thousands of dollars.
<h3>Exponential function:</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function for the value of the airplane after t years is given by:

Hence A(0) = 131.5, which means that the number 131.5 represents the initial value of the plane, in thousands of dollars.
