Both projects remove the required amount of pollutant from the river. But the two projects cause different costs and benefits over time, as given in the following table. a. Calculate the net present value (NPV) of project 1 using a discount rate of 3%. Show your work, and write your result in the blank provided. To receive marks, you must show work that leads to the answer you provide. Now suppose that the projects will impact three groups of Smoggyville's residents differently, according to the information in the following table. b. Is Project 1 horizontally equitable? (Use groups A and B to check.) c. Identify the vertical equity of Project 1. (Use groups B and C to check.)
