ECN801, V. Bardis Problem Set 41. (4.06) For an interest rate of 12% per year compounded every 2 months, determine the nominal interest rate per (a) 4 months, (b) 6 months, and (c) 2 years. 2. (4.10) An interest rate of 16% per year, compounded quarterly, is equivalent to what effective interest rate per year? 3. (4.23) A present sum of $5000 at an interest rate of 8% per year, compounded semiannually, is equivalent to how much money 8 years ago? 4. (4.25) Radio Frequency Identification (RFID) is technology that is used by drivers with speed passes at toll booths and ranchers who track livestock from farm to fork. Wal-Mart expects to begin using the technology to track products within its stores. If RFID-tagged products will result in better inventory control that will save the company $1.3 million per month beginning 3 months from now, how much could the company afford to spend now to implement the technology at an interest rate of 12% per year, compounded monthly, if it wants to recover its investment in 2½ years?

As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.
Temple University Fox School of Business ‘17, Course Hero Intern
I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.
University of Pennsylvania ‘17, Course Hero Intern
The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
