FNAN 301 Solutions to test bank problems – time value of money part 1 Some answers may be slightly different than provided solutions due to rounding 1. How much will you have in a. 16 years if you invest \$500 today at an annual rate of 5.6%? b. 14 years if you invest \$500 today at an annual rate of 5.6%? c. 18 years if you invest \$500 today at an annual rate of 5.6%? d. 18 years if you invest \$500 today at an annual rate of 6.6%? e. 18 years if you invest \$500 today at an annual rate of 4.6%? f. 18 years if you invest \$600 today at an annual rate of 4.6%? g. 18 years if you invest \$400 today at an annual rate of 4.6%? h. 18 years if you invest \$400 today at an annual rate of -4.6%? FV t = C 0 × (1+r) t For all of these problems: Step 1: investment value of several hundred dollars at year 0 and desired amount in 14, 16, or 18 years Step 2A: cash flow can be expressed as taking place in 14, 16, or 18 years and since 14, 16, and 18 are all whole numbers, a year is the largest period from this step Step 2B: no compounding period is given Step 2C: the interest rate that is given is for a year Step 2D: the shortest of the periods identified in steps 2A, 2B, and 2C is a year and is the length that each period on the timeline should reflect Step 3: the rate for a year is the rate that is given a. FV t = C 0 × (1 + r) t C 0 = 500; r = .056; t = 16 FV 16 = 500 × (1.056) 16 = 1,195.62 Mode is not relevant, since PMT = 0 Enter 16 5.6 -500 0 N I% PV PMT FV Solve for 1,195.62 b.

### What students are saying

• 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.

• 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.

• 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.
