A city's water treatment plant uses two processing stages. The first stage removes pp percent of contaminants, modeled by f(x)=x(1−p100)f(x) = x(1 - \frac{p}{100}) where xx is the initial contaminant level. The second stage removes qq percent of remaining contaminants, modeled by g(y)=y(1−q100)g(y) = y(1 - \frac{q}{100}). If p=60p = 60 and q=75q = 75, what is the overall efficiency as a single function h(x)h(x) representing the final contaminant level?
