MBA Corp plans to use its idle building that can potentially be rented for $15,000 per annum to set up a manufacturing machinery there. The current Revenue of MBA Corp is $500,000. If the company takes up this project, its revenue is expected to increase by 30% for the next three years and then double (from the 3rd year level) for the next two years. After 5 years, the project will be scrapped and the salvage value is expected to be $80,000 The COGS are expected to remain the same at 60% of revenue. The SG&A and other operating costs will increase by $10,000. The cost of the machinery is expected to be $250,000. The machinery installation cost is expected to be $20,000. This investment will require additional inventory of $40,000 and increase the accounts payable by $20,000 The company spent $ 5000 in researching the viability of the building for machine installation. The company hires you as a financial manager to advise if they should take up this project or not. Other information:…

3. Suppose you are to measure the BOD removal rate for a primary wastewater treatment plant. You take 2 samples of raw sewage on its way into the plant and two samples of the effluent leaving the plant. Standard 5-day BOD tests are run on the four samples, with no seeding producing the following data: Sample Dilution Doi (mg/L) DOf (mg/L) Source 1 Raw 1:30 9.0 2.2 2 Raw 1:20 9.0 ? 3 Treated 1:15 8.5 1.5 4 Treated ? 9.0 1 a. Find the BOD5 for the raw and treated sewage, and the percent removal of BOD in the treatment plant. b. Find the DO that would be expected in sample 2 at the end of the test. c. What would be the maximum volume of treated sewage for sample 4 that could be put into the 300 mL BOD bottle and still have the DO after 5 days remain above zero?

The three major steps in the QA process are Use objectives, fortification, blanks Use objectives, specifications, assessment Use objectives, false positives, raw data Fortification, blanks, calibration testing Raw data, treated data, results
