Create a class called candle to represent a candle. it should have four private instance variables: an int for the height, an int for the width, a float for the price and a boolean to determine if the candle is lit or not. the class should include a three-argument constructor (we will assume a constructed candle is not lit) and get and set methods for each instance variable. override the method tostring which should return the candle information in the same format as the input file

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)?
