I am so confused on how to answer this question given from my instructor. I see many websites that pertain to present value. Is there an explanation somewhere on the internet that would help explain? I googled the question and found"Net present value - Wikipedia, the free encyclopedia", and "NPV and IRR -- Measures for Evaluating Investments." The question given to us is:

Why is the present value of any future amount greater when the discount rate is lower?

Please help!
