The information provided allows us to set up the following system of linear equations:
We already have the value for A, solving the system gives us the values for B and C:
The total number of forms used is:
He used 440 forms.
The final value of the car will be given by:
final = origamt(1 - .20) to the 4th power. The car will retain therefore,only 80% of its original value from the preceding year for each of the 4 years starting with an original value of $35000.
