##### Experiments conducted by A.J. Clark suggest that the response $R(x)$ of a frog's heart muscle to the injection of $x$ units of acetylcholine (as a percent of the maximum possible effect of the drug) can be approximated by the rational function $$ R(x)=\frac{100 x}{b+x} \quad x \geq 0 $$ where $b$ is a positive constant that depends on the particular frog. a.
