The total energy savings are estimated to be $2,014 per year, and the cost of purchasing and installing the fluorescent fixtures is $5.200. The study period is six years, and terminal market values for the fixtures are negligible. a. What is the IRR of this investment? b. What is the simple payback period of the investment? C. Is there a conflict in the answers to Parts (a) and (b)? List your assumptions. d. The simple payback "rate of return" is 110. a. The IRR of the investment is %. (Round to one decimal place.) b. The simple payback period of the investment is years. (Round up to the next whole number.) c. Select all the correct assumptions below. A. The value of O may indicate the best project in terms of liquidity. B. The value of O may indicate a poor project in terms of liquidity. c. The IRR will signal an acceptable (profitable) project if the MARR is less than 31.1%. D. The IRR will signal an acceptable (profitable) project if the MARR is higher than 31.1%. d. The simple payback "rate of return", 110, is % (Round to one decimal place.)
