3. In addition to the data already provided, assume that due to the unique warming racks, the truck will have a $13,000 salvage value at the end of the six years. Under these conditions, compute the internal rate of return to the nearest whole percent. (Hint: You may find it helpful to use the net present value approach to find the discount rate that will cause the net present value to be closest to zero. Use the NPV approach with the following discount rates in mind: 9%, 11%, and 13%. Whichever rate gives you the NPV that is closest to zero, will be the answer.)
