The population $P$ of a certain city $y$ years after the last census is modeled by the equation below, where $r$ is a constant and $P_{0}$ is the population when $y=0$.
$P=P_{0}(1+r)^{y}$
If during this time the population of the city decreases by a fixed percent each year, which of the following must be true?
