Activity #1: programs to test writing functions – to be done individually. this activity is meant to give you more experience writing functions. in all cases, the key idea is to write a single function. however, in all cases, you should create a program that will essentially "test" the function. for example, you might include several function calls and the results, or create a program where a user can enter values and see the results. you may feel free to make multiple functions within any one of these programs.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
