Valley Corporation is attempting to select the best of a group of independent projects competing for the firm's fixed capital budget of $4,5 million. The firm recognizes that any unused portion of this budget will earn less than its 15% cost of capital, thereby resulting in a present value of inflows that is less than the initial investment. The firm has summarized, in the following table, the key data to be used in selecting the best group of projects:

ProjectInitial investmentIRRPV of inflows at 15%

A5,000,00017%5,400,000

B800,000181,100,000

C2,000,000192,300,000

D1,500,000161,600,000

E800,00022900,000

F2,500,000233,000,000

G1,200,000201,300,000

a. Use the internal rate of return(IRR)approach to select the best group of projects.

b. Use the net present value (NPV) approach to select the best group of projwcts.

c. Compare, contrast, and discuss your findings in parts a and b.

d. Which projects should the firm implement? Why?
