Check my work The Rustic Welt Company is proposing to replace its old well-making machinery with more modern equipment. The new equipment costs $9.4 million (the existing equipment has zero salvage value). The attraction of the new machinery is that is expected to cut manufacturing costs from their current level of $8.40 a welt to $4.40. However, as the following table shows, there is some uncertainty about both the future sales and the performance of the new machinery Pessimistic Expected Optimistic Sales (million weits) 0.8 0.9 1.1 Manufacturing cost (per wait 6.40 4.40 3.40 Life of new machinery (years) 4 7 10 Conduct a sensitivity analysis of the replacement decision assuming a discount rate of 1%.
