Expenses associated with heating and cooling a large manufacturing facility owned by Nippon Steel are expected to increase according to an arithmetic gradient. If the cost is $550,000 now (i.e., year 0) and the company expects the cost to increase by $40,000 each year through year 12, what is the equivalent annual worth in years 1-12 of the energy costs at an interest rate of 10% per year? 1) Draw a cash flow diagram of the current contract and a cash flow diagram of the equivalent annual worth. Please specify values of every terminology. Give a question mark if unknown yet. 2) Compute the equivalent present value at year -1. (Draw cash flow diagrams to indicate how you separate the original cash flow diagram. Find the equivalent present value at year -1 for each diagram.) 3) Compute the equivalent present value at year 0. 4) Compute the equivalent annual worth in years 1-12
