Basic Internal Rate of Return Analysis For discount factors use Exhibit 12B-1 and Exhibit 12B-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. Required: 1. Calculate the project's IRR. (Round your answer to the nearest percent.) % Should the company acquire the new cooling system? 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.) $per year 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 your answer to the nearest dollar.)
