Windhoek Mines, Limited, of Namibia, is contemplating the purchase of equipment to exploit a mineral deposit on land to which the company has mineral rights. An engineering and cost analysis has been made, and it is expected that the following cash flows would be associated with opening and operating a mine in the area: Cost of new equipment and timbers $ 420,000 Working capital required $ 230,000 Annual net cash receipts $ 165,000 Cost to construct new roads in year three $ 66,000 Salvage value of equipment in four years $ 91,000 *Receipts from sales of ore, less out-of-pocket costs for salaries, utilities, insurance, and so forth. The mineral deposit would be exhausted after four years of mining. At that point, the working capital would be released for reinvestment elsewhere. The company's required rate of return is 18% Click here to view Exhibit 128-1 and Exhibit 12B-2, to determine the appropriate discount factor(s) using tables. Required: a.

Investment Profitability Proposal Index Rank Preference A B D The management of Ballard MicroBrew is considering the purchase of an automated bottling machine for $43,000. The machine would replace an old piece of equipment that costs $11,000 per year to operate. The new machine would cost $5,000 per year to operate. The old machine currently in use is fully depreciated and could be sold now for a salvage value of $17.000. The new machine would have a useful life of 10 years with no salvage value. Required: 1. What is the annual depreciation expense associated with the new botting machine? 2. What is the annual incremental net operating income provided by the new bottling machine? 3. What is the amount of the initial investment associated with this project that should be used for calculating the simple rate of return? 4. What is the simple rate of return on the new bottling machine? (Round your answer to 1 decimal place le. 0.123 should be considered as 12.3%) 1. Depreciation exponse 2. Incremental net operating income 3. Initial investment 4. Simple rate of return %
