Basic Internal Rate of Return Analysis

OKAY FOLKS THE EXHIBITS ARE AT THE BOTTOM. I need an answer to #4 - a written answer I can at least use as a reference when writing my own.

For discount factors use Exhibit 14B-1 and Exhibit 14B-2.

Julianna Cardenas, owner of Baker Company, was approached by a local dealer of air-conditioning units. The dealer proposed replacing Baker's old cooling system with a modern, more efficient system. The cost of the new system was quoted at $339,000, but it would save $60,000 per year in energy costs. The estimated life of the new system is 10 years, with no salvage value expected. Excited over the possibility of saving $60,000 per year and having a more reliable unit, Julianna requested an analysis of the project's economic viability. All capital projects are required to earn at least the firm's cost of capital, which is 8%. There are no income taxes.

2. Suppose that energy savings are less than claimed. Calculate the minimum annual cash savings that must be realized for the project to earn a rate equal to the firm's cost of capital. Round your answer to the nearest dollar.

3. Suppose that the life of the new system is overestimated by 2 years. Repeat Requirements 1 and 2 under this assumption.

Calculate the project's internal rate of return.

Should the company acquire the new cooling system?

Calculate the minimum annual cash savings that must be realized for the project to earn a rate equal to the firm's cost of capital. (Round to the nearest dollar)

4. Conceptual Connection: Explain the implications of the answers from Requirements 1, 2, and 3.
