Given

Crunch (x is in R)

if \(\displaystyle{x}\Rightarrow{100}\) then

returen \(\displaystyle\frac{{x}}{{100}}\)

else return \(x+\)Crunch \(\displaystyle{\left({10}\cdot{x}\right)}\)

We need to compute Crunch(117)

\(x=117\)

Since 117 is at least 100, we need to execute the then-statement "return \(\displaystyle\frac{{x}}{{100}}\)" and thus we need to divide the input \(x=117\) by 100:

\(\displaystyle\frac{{x}}{{100}}=\frac{{117}}{{100}}={1.17}\)

Thus Crunch \((117)=1.17\)
