The company requires a minimum rate of return (Ignore income taxes for this problem.) Required: 1. Determine the net present value (NPV) of the proposed inve sent Value (NPV) of the proposed investment. (The PV annuity factor for 12%, 7 years is 4.564.) Round your answer to the nearest whole number. 2. Determine the project's estimated internal rate of ne the project's estimated internal rate of retum (IRR), rounded to the nearest tenth of a percent. (Note: PV annuity factors for 7 years: @ 10% = 4.868; @ 11% = 4.112 4.564; @ 13% = 4.423; @ 14%= 4.288: @ 15% = 4.160; and, @ 20% = 3.605.) 3.
