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.
The calculation is
[tex]final \: value \\ = (35000) {(.8)}^{4} \\ = 35000 \times .4096 \\ = [/tex]
A measely $14,336!
