Answer:
If the truck's value dropped 15% each year, after one year the value of the truck is 22000*(1-0.15) = $18700
After the second year, the value of the truck would be 18700*(1-0.15) = $15995
After the third year, the value of the truck would be 15995*(1-0.15) = $13596.75
Rounding the answer to the nearest dollar, the value of the truck after 3 years is $13597
