Final answer:
The statement that units per transaction are the total number of items within each transaction is TRUE. In business, this refers to the quantity of items sold or purchased per transaction. Examples from daily life and chemistry highlight the importance of using specific numerical units for counting.
Step-by-step explanation:
Units per transaction refer to the total number of items that are sold or purchased in each individual transaction. This statement is TRUE. Just like everyday items that are sold in specific quantities, such as a six-pack of soda or a dozen of eggs, each transaction in a business setting involves a certain number of units. These units can vary greatly depending on the item being sold. For example, a retail store may sell individual items, each counting as one unit, or they might sell items in bulk, where each package contains multiple units.
Moreover, in fields like chemistry, there are examples of extremely large quantities used to count very small entities, such as atoms in a mole, which is equivalent to Avogadro's number (6.022 x 1023 atoms). Although this concept is a bit different from units per transaction in a business context, it illustrates the use of numerical units to quantify items.
