Answer: 7 years
Explanation:
Given: The initial price of truck = $32,000
The value of the truck after t years can be represented by the formula ,

To find the time t in years after which the worth of the truck will be approximately $6700, we need to substitute V=6700 in the equation, we get

Taking log on both sides, we get

Hence, after 7 years the worth of the truck will be approximately $6700.
