A factory selling cell phones has a marginal cost function C(x) = 0.01x2 – 3x + 229, where x represents the number of cell phones, and a marginal revenue function given by R(x) = 429 – 2x. Find the area between the graphs of these curves and x = 0. What does this area represent?

P11-25 Integrative—Determining relevant cash flows Lombard Company is contemplating the purchase of a new high-speed widget grinder to replace the existing grinder. The existing grinder was purchased 2 years ago at an installed cost of $60,000; it was being depreciated under MACRS using a 5-year recovery period. The existing grinder is expected to have a usable life of 5 more years. The new grinder costs $105,000 and requires $5,000 in installation costs; it has a 5-year usable life and would be depreciated under MACRS using a 5-year recovery period. Lombard can currently sell the existing grinder for $70,000 without incurring any removal or cleanup costs. To support the increased business resulting from purchase of the new grinder, accounts receivable would increase by $40,000, inventories by $30,000, and accounts payable by $58,000. At the end of 5 years, the existing grinder would have a market value of zero; the new grinder would be sold to net $29,000 after removal and cleanup costs and before taxes. The firm is subject a 40% tax rate. The esti- mated earnings before depreciation, interest, and taxes over the 5 years for both the new and the existing grinder are shown in the following table. (Table 4.2 on page 117 contains the applicable MACRS depreciation percentages.) Year Earnings before depreciation, interest, and taxes New grinder Existing grinder $43,000 $26,000 43,000 24,000 43,000 22,000 43,000 20,000 43,000 18,000 a. Calculate the initial investment associated with the replacement of the existing grinder by the new one. b. Determine the incremental operating cash inflows associated with the proposed grinder replacement. (Note: Be sure to consider the depreciation in year 6.) c. Determine the terminal cash flow expected at the end of year 5 from the pro- posed grinder replacement. d. Depict on a time line the relevant cash flows associated with the proposed grinder replacement decision.

To calculate the actual depreciation for tax purposes, be sure to apply the actual unrounded percentages or directly apply double-declining balance depreciation using the half-year convention.

please take screen shot of every step sk that i can know how you did them. HANDS-ON ACTIVITY 2A Tracing Your Email Most email today is spam, unwanted commercial email, or phishing, fake email designed to separate you from your money. Criminals routinely send fake emails that try to get you to tell them your log-in information for your bank or your PayPal account, so they can steal the information, log-in as you, and steal your money. It is very easy to fake a return address on an email, so sim- ply looking to make sure that an email has a valid sender is not sufficient to ensure that the email was actually sent by the person or company that claims to have sent it. However, every SMTP email packet contains information in its header about who actually sent the email. You can read this infor- mation yourself, or you can use a tool designed to simplify the process for you. The objective of this Activity is for you to trace an email you have received to see if the sending address on the email is actually the organization that sent it. There are many tools you can use to trace your email. We like a tool called eMail Tracker Pro, which has a free version that lasts 15 days. 1. Go to www.emailtrackerpro.com and download and install eMail Tracker Pro. 2. Log-in to your email and find an email message you want to trace. I recently received an email supposedly from Wachovia Bank; the sender's email address was aw-login@wachovia.com. 3. Alter you open the email, find the option that enables you to view the Internet header or source of the mes- sage (in Microsoft Outlook, click the Options tab and look at the bottom of the box that pops up). Figure 2-19 shows the email I received and how to find the SMTP header (which Outlook calls the Internet header). Copy the entire SMTP header to the clip- board. 4. Start eMail Tracker Pro. Select Trace an email, and paste the SMTP header into the box provided. Click Trace to start the trace. 5. It may take up to 30 seconds to trace the email, so be patient. Figure 2-20 shows the results from the email I received. The email supposedly from Wachovia Bank was actually from a company named Musser and Kouri Law whose primary contact is Musser Ratliff, CPA, which uses SBC in Plano, Texas, as its Internet service provider. We suspect that someone broke into this company's network and used their email server without permission, or fraudulently used this com pany's name and contact information on its domain registration De Trace one email. Print the original email message and the trace results.
