1. Develop a cash flow diagram for the following scenario:
   • A township is considering creating new athletic facilities for an initial construction cost of $225,000.
   • Initial annual O&M costs will be $85,000, and will increase by $5,000 per year for every subsequent year.
   • Its estimated the new facilities will bring in $190,000 in annual revenue.
   • At the end of year 6, the facility will need an overhaul costing $75,000.
   • The salvage value will be $100,000 after 10 years.

2. How long will it take for an investment to double at a 4% interest rate compounded annually? (using interpolation to solve this problem with compound interest tables is acceptable but not required).
