Purcase price is 8000

30% of purchase price is 2400

market value after 2 years is 8000-2400-2400==>3200

So C is the answer

Thanks. I guess the only way for me to really know is to get inside of your mind but how did you know it was 2400 each year instead of 30% each year....I guess my question is what key word did you use to decipher between the two?

30 % of 8000==>30/100*8000==>2400
