MIS 3003 Chapter 3 Homework

3-1. Figure AE-1 shows an Excel spreadsheet that the resort bicycle rental business uses to value and analyze its bicycle inventory. Examine this figure to understand the meaning of the data. Now use Excel to create a similar spreadsheet. (4 pts)

a. Figure AE-1 uses the following formulas:

Cost of Current Inventory = Bike Cost * Number on Hand.
