Elizabeth Burke has asked you to do some preliminary analysis of the data in the Performance Lawn Equipment Database.xlsx. First, she would like you to edit the worksheets Dealer Satisfaction and End-User Satisfaction to display the total number of responses to each level of the survey scale across all regions for each year. Second, she wants a count of the number of failures in the worksheet Mower Test. Next, Elizabeth has provided you with prices for PLE products for the past 5 years:

Year	Mower Price	Tractor Price
2010	150	3250
2011	175	3400
2012	180	3600
2013	185	3700
2014	190	3800

Create a new worksheet in the database to compute gross revenues by month and region, as well as worldwide totals, for each product using the data in Mower Unit Sales and Tractor Unit Sales. Finally, she wants to know the market share for each product and region based on the PLE and industry sales data in the database. Create and save these calculations in a new worksheet. Summarize all your findings in a report to Ms. Burke.
