~only answer if you know for sure~
you bought a car for $20,000. you have owned it for one year, and it is now worth $16,000. what is the percent decrease in your car's value?
20%
25%
80%
125%

Option A. 20%

Step-by-step explanation:

Since the cost price of the car when it was new = $20000

After one year car value $16000.

We have to calculate the depreciation in the price or my car.

So decease in the car's value = 20000-16000 = $4000

Since cost price of the car was = $20000

therefore % decrease decrease in the price will be = (decrease in price/cost price)×100 = (4000/20000)×100 = 20%

i believe it's a.

i'm not sure on this one, most likely correct.
