What method demonstrates the present worth of a single future payment of $1?

The method that demonstrates the present worth of a single future payment of $1 is the present worth of $1. This concept is fundamental in time value of money calculations, where the value of money is understood to change over time. The present worth of a single future payment is determined using a discount rate and reflects how much a future sum of money is worth in today's terms.

By using the present worth of $1 method, you can calculate the current value of a dollar that you expect to receive in the future. This approach is essential for various financial evaluations, including investment analyses, to assess the value of cash flows over time. It allows stakeholders to make informed decisions on investments and pricing by translating future amounts into present value.

The other options do not effectively represent this specific financial calculation. Partial payment factors pertain to different aspects of payment structures, contingency tables are used primarily in statistics for organizing categorical data, and cross tabulation is a method for examining relationships between variables. None of these methods provide the same direct calculation of present value for a future single payment.
