Final answer:
To estimate linen usage, multiply the number of occupants by the average pounds of linen used per occupant, using dimensional analysis—a method that ensures proper manipulation of units in calculations.
Step-by-step explanation:
The calculation in question is a practical application of dimensional analysis, commonly used in both mathematics and sciences, which involves a step-by-step approach to apply mathematical operations to quantities with their respective units. The number of expected occupants (or covers) and the average pounds of linen used are critical factors. To estimate the total linen usage for a specific number of people or 'covers', you would multiply the number of occupants by the average pounds of linen used per occupant. This process is similar to calculating the multiplier in economic scenarios. Dimensional analysis ensures that the units involved in the calculations are correctly manipulated, thereby providing a reliable estimate of the total amount of linen required. When dealing with customary units such as pounds and ounces, or when converting between different units of measurement, this method is particularly useful.
