Say that you are the sales manager of a company that produces software for human resource departments.

You are planning your staffing needs, which depend on the volume of sales over time. Your company currently sells \($350\) million of merchandise per year and has grown 7 percent per year in the past. If this growth rate continues, how long will it be before the firm reaches \($500\) million in sales?

How long before it reaches \($600\) million?
