Final answer:
Calculation of the Internal Rate of Return (IRR) requires identifying the discount rate that will make the Net Present Value (NPV) of all cash flows from the investment equal to zero. The NPV equation is complex, often requiring the use of a financial calculator or software to find IRR through iterative methods. If the discount rate of 14 percent makes NPV zero for the given jelly bean-making machine case, then it represents the IRR, else we must further iterate to find the exact IRR.
Step-by-step explanation:
The calculation for Internal Rate of Return (IRR) involves finding the discount rate that makes the net present value (NPV) of all cash flows from an investment equal to zero. For the new jelly bean-making machine, the management of Robert Williams expects an annual cash flow of $114,220 over seven years with an initial cost of $290,000. To determine the IRR, we would typically use a financial calculator or software because the calculation involves solving for the rate in the NPV equation through iteration. However, the provided question asks for the IRR assuming a discount rate of 14 percent. Since IRR is the rate at which NPV equals zero, and if 14 percent were the IRR, then the NPV would be zero at this rate. But we must verify this by finding the present values of each annual cash flow at a 14 percent discount rate and then summing these to compare with the initial investment.
If the sum of the discounted cash flows equals the initial cost of the machine, then 14 percent is indeed the IRR. If not, we would then test different rates until the NPV equals zero. However, the calculation would be more complex, involving trial and error or using NPV tables or financial calculators. The example given about the bond calculation helps illustrate the concept of present value adjustments due to changes in discount rates, a critical part of determining IRR.
