The value of a dirt bike decreases by 25% 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?

a.) $84
b.) $119
c.) $164
d.) $222

The value of the bike at any year n is calculated through the equation,
                          At = (A1) x (1 - r)^n
Substituting the known values,
                          At = ($500) x (1 - 0.25)^5 = $118.65
Thus, the bike would cost only $118.65 after 5 years and the answer is letter B.
