To calculate the value of the personal watercraft after two years, we can use the given depreciation rate of 13%. The common ratio for the geometric sequence is 0.87, meaning that the value after each year is multiplied by 0.87.
-
First Year: The initial value is $6,500. After one year: \[ \text{Value after Year 1} = 6500 \times 0.87 = 5,655 \]
-
Second Year: Now, we take the value after the first year and apply the same depreciation: \[ \text{Value after Year 2} = 5655 \times 0.87 \] Calculating this: \[ 5655 \times 0.87 = 4,919.85 \]
Rounding to the nearest whole dollar, the value after two years is approximately $4,920.
Therefore, the correct answer is: $4,920.
