Last months sales of the ET electric truck were 25,400 units. The company anticipates a 5 monthly sales growth of 0.5%. Currently, one competitor is developing an equivalent

truck. In the month that the competitors truck enters the marketplace, sales of the ET

electric truck is expected to decrease by 1%. Create an Excel spreadsheet that will

compute the monthly sales for the next 24 months. Your spreadsheet should allow the user to enter the date the competitor enters the marketplace, and your sales computations should reflect the change in sales when the competitor enters.

**THE USER SHOULD BE ABLE TO CHANGE THE DATE IN WHICH THE COMEPETITORS ENTER AND THE DATA SHOULD DECREASE BY 1% STARTING FROM THAT MONTH**
