A $17,000 motorcycle depreciates at a rate of 5% each year. Write an exponential function to model this situation.

Answer 1

if it decreases by r% per year, then if the starting value is v0,
v(y) = v0 * (1-r/100)^y
see the two problems below this one, posted under other names ...

Answer 2

17 000 (1 - 0.05)^y
