Which of the following methods is NOT part of figuring a formula price?

To understand why "none of these" is the correct answer, it’s essential to consider what is meant by figuring a formula price in the context of mortuary administration. Formula pricing typically involves various methods to determine the total price of services and goods provided by a funeral home.

The functional method refers to pricing based on the specific functions or services a funeral home provides, emphasizing the value of those services. The unit method calculates the price based on a single unit of service or product, such as a casket. The bi-unit method is a variation that combines both fixed and variable components in the pricing structure, reflecting both services and merchandise.

Since all the listed methods—functional, unit, and bi-unit—are indeed methods used in determining a formula price, selecting "none of these" correctly identifies that all the options given are valid methods within this framework. There are no options presented that are outside the scope of methods used to calculate formula pricing, supporting why "none of these" is the appropriate response.
