hello all, please i need you help to solve the following true and false questions,

[1] True or False? (30 points)

(1) Company Y has three investment projects (A, B and C) and can only spend 40 million. Project A has an initial investment of 20 million, and is expected to produce a Net Present Value (NPV) of 28; Project B has an initial investment of 40 million, and is expected to produce a NPV of 54; Project C has an initial investment of 20 million, and is expected to produce a NPV of 29. According to the Profitability Index, Company Y should accept project B, because it has the greatest present value. Is that last statement true or false?

(2) The Internal Rate of Return is the rate of return expected by those who provide capital for the business (debt and equity).

(3) In order to minimize their Weighted-Average Cost of Capital (WACC), companies need always to have the highest possible credit rating, because that guarantees the lowest possible credit spread.

(4) When an investment projects assets are likely to become obsolete at the end of the project life (computer hardware), it makes sense to estimate a zero salvage value.

(5) The acquisition of a firm can be evaluated with the same tools (Net Present Value) that are used in conventional project valuation.

(6) Assume that you have analyzed a $100 million project using a cost of capital of 15% and come up with an NPV of $1 million. The manager who has to decide on the project argues that this NPV is too small for a project of this size and that this indicates a poor project. Is this last statement true or false?
