The value of a dirt bike decreases by 20% each year. if you purchased this dirt bike today for $500, to the nearest dollar how much would the bike be worth 5 years later?

The value of the bike after a year becomes only 80% of the value a year ago. In this given, the initial amount $500 should be multiplied by 80% 5 times. The answer would be $163.84. Thus, after 5 years the dirt bike would only be $163.84.
