Given:

Cell Phone Service, x=$36.45 per month

Landline Phone Service, y= $30.11 per month

Cable TV Service, z=$57.43 per month

Internet Service, p= $37.32 per month

The price for a package of all services, P=$131.59.

The total price of services before purchasing the package is,


T=36.45+30.11+57.43+37.32=161.31

Now, the percentage decrease by purchasing the package is,


\begin{gathered} \text{Percentage}=(T-P)/(T)*100 \\ =(161.31-131.59)/(161.31)*100 \\ =18.4 \end{gathered}

Therefore, the percentage decrease by purchasing the package is 18.4%.
