Engineers with Monarch Paints have recommended to management investment of $250,000 now in novel methods that will reduce the amount of wastewater, packaging materials, and other solid waste in their consumer paint manufacturing facility. Estimated savings are $180,000 per year for each of the next 7 years and an additional savings of $25,000 at the end of 7 years in facility and equipment upgrade costs. Annual expenses will be $100,000 at the end of year one and will increase by $6,500 each year thereafter. 1. Draw the cash flow diagram 2. What is the simple payback period of the furnace? 3.
