*Two systems are under consideration. The relevant costs for each system are known or estimated (see table below). Use an interest rate of 15% per year to determine the minimum resale price (RV) needed to make the challenger a better economic choice now. Calculations based on interest factors with 5 decimal places. Current New System System Remaining life, (years) Current market value, (S) AOC, (S per year) Future salvage, (S) AW New System, ($ per year) 50,000 -100,000 -195,000 O RV= $318,450 O RV= $653,670 O RV- $326,147 O RV= $988,871
