Note. To save your work, click Done. Do not click the X button to exit MyFinanceLab as it will result in data loss. Please note that once you complete the lab your score will not automatically be posted to your gradebook. I will manually do this on the Tuesday after the week ends. You may continue to work on the lab for 4 days after the week ends for a 10% deduction each day. I determine the last day worked on the lab by the time stamp in the lab for those problems. Keep this in mind if you go back in the lab later in the week. Also the lateness penalty is on the entire weeks assignment, not on a problem by problem basis.

For this week I included some spreadsheets and problems to illustrate how to work these problems in Excel.
