Pearl Manufacturing is considering an investment in equipment costing $660,000. The equipment will be depreciated on the straight-line basis over an eight-year period with an estimated residual value of $120,000. Using the accounting rate of return model, what is the minimum average annual operating income that must be generated from this investment in order to achieve a 6.38% accounting rate of return? Let's think of it this way: Use Table 3-10 as a model for computing the average investment. That's the denominator. The question asks for the Operating income. Use the model on pages 117-118. There are no taxes in this problem. Select the response to the nearest $100.
