B. Sara said the value of the car decreased by 88% over the past year.
C. Sean said the value of the car increased by 88% over the past year.
D. None of them are correct.

Answer 1

The correct interpretation of the value of the car is option A. Victor said the value of the car decreased by 12% over the past year.

Step-by-step explanation:

The correct interpretation of the value of the car is option A. Victor said the value of the car decreased by 12% over the past year.

To find the percentage decrease in the value of the car, we subtract the final value from the initial value and divide by the initial value. In this case, the initial value is æ dollars and the final value is 0.88t. So the percentage decrease is (æ - 0.88t) / æ.

Since we are told that the value of the car decreased, the correct option is the one that indicates a decrease, which is option A. Victor said the value of the car decreased by 12% over the past year.
