Upon review, assume the following changes to the above information:

A. The investment cost of Alternative A increased to 300,000.

B. The first EOY cash flow of Alternative B is actually +20,000.

C. The salvage value of Alternative C is actually 25,000.

Round all your answers to 2 decimal places, do not round intermediate solutions. For questions #7, 10, and 12, just type in the letter of the alternative.
