In an automated drone navigation system, the power consumption rate PPP (in watts) depends on the aerodynamic efficiency factor S S\,S and the payload penalty WWW.
The drone has a baseline power consumption of 180 watts. This baseline is adjusted by dividing it by the aerodynamic efficiency factor (SSS), and then adding a payload penalty (WWW) measured in watts.
Construct an algebraic expression to calculate the total power consumption rate (PPP).
