Create an algorithm that tells someone how to evaluate the following expression: 7 * 5 – 20 / 2 + 4 * 2. the / operator means division, and the * operator means multiplication. (as you may remember from your math courses, division and multiplication are performed before addition and subtraction.) zak, diane. an introduction to programming with c++ (p. 18). cengage learning. kindle edition.

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)?
