Answer: at the end of year 9 the car value would be $9963,5
Step by step:
Every year you lose 6.30% of the last value, so from the last year's value you take out another 6.3%.
every year the formula is the same, so based on first year it would be:
$17896 * (100%-6.3%) = $17896 * 93.5% = $16768.6
year 1 17896,0 6,30%
year 2 16768,6 6,30%
year 3 15712,1 6,30%
year 4 14722,3 6,30%
year 5 13794,8 6,30%
year 6 12925,7 6,30%
year 7 12111,4 6,30%
year 8 11348,4 6,30%
year 9 10633,4 6,30%
end of year 9 = 9963,5
