DS: If the market value of a car was $6000 exactly 3 years ago, what is its current market value? (1) starting at the time of purchase, the market value of the car depreciated at 20% of its purchase price per year; (2) the current market value of a car manufactured in the same year is $2400. Why the answer is E? I think (1) and (2) can be sufficient by their own, so my answer could be D. Thank you!!

The question asks for the "market value" of a car. Market value is different from the car value after depreciation. 1) only mentions the value after 3 years depreciation 2) mentions a car manufacturered in the same year is worth $2,400.00 now, but it does not say whether this is the same brand as stated in the question. (also type of engine, color of the car, leather seat and other features...etc) so 1) and 2) both cannot determine the market value of that car, and answer is E hope this help!
